How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security89
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- The endpoint enforces authorisation, advertised via RFC 9728 protected-resource metadata. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability0
- Transport blocked by authentication: the endpoint requires auth we don't have to verify streamable-http. See how to fix → View diagnostics → Unverified
Schema Quality & AI Usability0
- Schema blocked by authentication: the endpoint requires auth we don't have to read it. See how to fix → Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage blocked by authentication: the endpoint requires auth we don't have to read its tools.Unverified
Tool Safety0
- Tool safety blocked by authentication: the endpoint requires auth we don't have to read its tools.Unverified
Capabilities0
- Capabilities blocked by authentication: the endpoint requires auth we don't have to read them. See how to fix → Unverified
Unverified: 6 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm. Claim this server and supply a read-only token to verify it and lift the score.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
cypher_link_root_cause Link root cause ~181
Point an issue at the code symbol that caused it.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds npub. Either the grant envelope that receive_npub_proof returned, or the raw JSON of a kind-27235 Nostr event signed by npub: content "", a `u` tag holding this tool's exa… |
| issue_number | integer | yes | GitHub issue number. |
| npub | string | – | The patron's Nostr public key (npub1...). Tool fees are paid from this patron's balance; dpop_token proves the caller holds it. |
| repo_name | string | yes | Repository name. |
| symbol_fqn | string | yes | Fully-qualified name of the code symbol at fault. |
No output schema declared.
No examples provided.
cypher_list_canonical_identities Tool identities ~250
Return canonical (tool_id, mcp_name, …) for every tool the wheel exposes. The authoritative source for any client (Studio, agents, FE) that needs to know how this MCP identifies its tools. Reconcile uses this output to UUID-join against the stored pricing model — no name-based UUID derivation, no guessing. Includes both ToolIdentity-seeded tools and any UUID recorded by ``@paid_tool`` that is missing from the registry. The latter appear with ``registered: false`` (and in the top-level ``unregistered`` array) so Reconcile can flag deploy drift instead of silently reporting clean when a live tool was never seeded (#174). If the operator renames a function or rebrands a slug, the mcp_name in this output changes but tool_id stays. That's the whole point of the canonical-UUID design. Also diffs the live FastMCP wire surface against the registry. Tools exposed on the wire but absent from the registry appear in ``unregistered`` so Reconcile can flag deploy drift instead of silently under-reporting (issue #175). Free, no side effects.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
cypher_list_capabilities List capabilities ~162

| dpop_token | string | – | Proof that the caller holds npub. Either the grant envelope that receive_npub_proof returned, or the raw JSON of a kind-27235 Nostr event signed by npub: content "", a `u` tag holding this tool's exa… |
| npub | string | – | The patron's Nostr public key (npub1...). Tool fees are paid from this patron's balance; dpop_token proves the caller holds it. |
| since_ms | integer | – | Epoch-ms lower bound on change time; 0 (default) = any time. |
No output schema declared.
No examples provided.
cypher_list_constraint_types Constraint types ~51
List all available constraint types and their parameter schemas. Returns the type, category, description, and parameter specs for every constraint that can be used in a pricing pipeline. Free — no credits required.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
cypher_list_coupons Coupons ~122
List every coupon this operator has minted (newest first). Each row carries the current ``times_redeemed`` counter — the Studio renders a progress bar from this against ``total_uses``. RESTRICTED to operator — requires proof.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds the operator's npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by the operator whose `u` tag is this tool's name. |
Structured output declared, but exposes no named fields.
No examples provided.
cypher_list_invariants List invariants ~159

No output schema declared.
No examples provided.
cypher_list_my_coupons My coupons ~148
List the coupons this patron has redeemed on this operator. Returns both active and exhausted redemptions with a per-row ``status`` (``active`` / ``window_closed`` / ``patron_limit`` / ``total_limit``). Free — requires proof of ``npub``.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |
| npub | string | yes | The patron's Nostr public key (npub1...). |

cypher_mint_coupon Mint coupon ~279
Create a new operator-owned discount coupon. The coupon owns its binding: ``tool_ids`` names the tools it discounts, and re-pricing a tool never touches it. A coupon bound to no tool discounts nothing, however many patrons redeem it.
| Name | Type | Req | Description |
|---|---|---|---|
| discount_percent | number | yes | Percentage off the base price (0-100). |
| dpop_token | string | – | Proof that the caller holds the operator's npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by the operator whose `u` tag is this tool's name. |

cypher_public_factory_stats Public factory stats ~127
Aggregate-only factory stats for the unauthenticated landing pages. Free — no credits, no npub proof. Returns counts only (capabilities, invariants, issues, services, symbols), the resolved_via mix (graph | scoped-grep | wide-grep), and a last-activity timestamp. Never returns issue titles, symbol paths, or npubs. Hard-cached in-process (~5 min) so a sleeping AuraDB free tier is not woken on every page view. Safe for cold Bolt: failures return an empty available=false payload rather than raising.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
cypher_publish_nostr_profile Publish Nostr profile ~150
Publish a CLIENT-SIGNED kind-0 profile to relays for an npub. The wheel never holds a patron nsec. The frontend signs the kind-0 metadata event with the patron's session key or a NIP-07 extension and passes the signed event (JSON) here; the wheel verifies the signature matches the npub, then relays it to public relays. The signature is the authorization — no proof token, no key custody. Free.
| Name | Type | Req | Description |
|---|---|---|---|
| npub | string | – | The patron's Nostr public key the event must be signed by. |
| signed_event | string | – | A JSON-encoded, client-signed kind-0 event. |
Structured output declared, but exposes no named fields.
No examples provided.
cypher_publish_tool Publish a query as a tool ~329
Operator-only: expose a catalog query as a named, typed MCP tool. Projects the published query as a first-class tool named ``cypher_<key>`` whose flat, typed parameters come from the query's param schema (e.g. ``cypher_which_service_handles(keyword)``). The tool is registered immediately but starts **unpriced** — it appears in Pricing Studio like any new tool; set its price there. Until priced, calls return "not priced yet (TBD)". Patrons then call it by name with typed params instead of ``execute_query_by_key``. The key must be a valid tool identifier (^[a-z][a-z0-9_]*$). Reconnect to see the new tool in the tool list.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds npub. Either the grant envelope that receive_npub_proof returned, or the raw JSON of a kind-27235 Nostr event signed by npub: content "", a `u` tag holding this tool's exa… |
| key | string | yes | An existing catalog query key (see ``list_queries``). |
| npub | string | – | The patron's Nostr public key (npub1...). Tool fees are paid from this patron's balance; dpop_token proves the caller holds it. |
| tool_intent | string | – | One-line description shown as the tool's purpose (defaults to the query's description). |
Structured output declared, but exposes no named fields.
No examples provided.
cypher_purchase_credits Buy credits ~157
Buy credits via Bitcoin Lightning. Creates a Lightning invoice. Pay it with any Lightning wallet, then call check_payment to confirm. Proof of npub ownership is required so credits land in the correct ledger. Free — no credits required to call.
| Name | Type | Req | Description |
|---|---|---|---|
| amount_sats | integer | – | Satoshis to purchase (default 1000). |
| dpop_token | string | yes | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |
| npub | string | yes | The Nostr public key (npub1...) the credits will fund. |
Structured output declared, but exposes no named fields.
No examples provided.
cypher_receive_credentials Receive credentials ~354
Pick up credentials from the Secure Courier. Completes the CREDENTIAL-DELIVERY flow (the ownership-proof counterpart is ``receive_npub_proof``). **Call this only after the user confirms they have replied.** Deterministic, one-shot retrieval: name the response you want with ``(sender_npub, service, dpop_token)`` and the tool drains ONLY the rendezvous relay that channel was pinned to. Every popped DM with the wrong session phrase is deleted and its sender is NACK'd; the first DM with the matching phrase is accepted (ACK'd) and the scan stops. If none match, the queue is drained and a ``courier_not_found`` result is returned. Do NOT poll, loop, or retry. If a credential_card (ncred1...) is provided, it is redeemed directly without any relay access (dpop_token not required for that path). On success, the payment processor client is reinitialized from the new credentials — no server restart needed.
| Name | Type | Req | Description |
|---|---|---|---|
| credential_card | string | – | Optional. An ncred1... card to redeem directly (bypasses the relay drain; dpop_token not needed). |
| dpop_token | string | – | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |
| sender_npub | string | – | Required. The npub that sent the credentials. |
| service | string | – | Required. The credential service name (must match the service used in request_credential_channel). |
Structured output declared, but exposes no named fields.
No examples provided.
cypher_receive_npub_proof Receive npub proof ~363
Receive npub ownership confirmation from a patron. Completes the npub-OWNERSHIP-PROOF flow (the credential-delivery counterpart is ``receive_credentials``). **Call this only after the user confirms they have replied.** Deterministic, one-shot retrieval: name the response with ``(patron_npub, dpop_token)`` — the ``dpop_token`` being the value returned by ``request_npub_proof``. The tool drains ONLY the pinned rendezvous relay that challenge was published on, stopping at the DM whose phrase matches. Mismatched DMs are deleted and NACK'd (without revealing the expected phrase). If called before the user replies, their message will never be found. Do NOT poll, loop, or retry. The signed DM itself proves npub ownership (the patron's nsec signed it). On success, returns a new ``dpop_token``: an Operator-signed **proof grant envelope** ``{"grant": …, "nonce": …}`` bound to the patron, this challenge, and the duration the patron named. The calling application MUST remember that whole string and pass it as ``dpop_token`` on every subsequent paid tool call. The grant is self-verifying; nothing about it is stored here. Free.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |

cypher_redeem_coupon Redeem coupon ~199
Claim a coupon by its name (the code the operator shared). Looks up the operator's coupon by ``code``, validates the window and total cap, and records a per-patron redemption row. Subsequent paid tool calls on this MCP auto-apply the discount until ``uses_per_patron`` is exhausted. Free — no credits required. Requires proof of ``npub``. Idempotent: redeeming the same code twice returns the existing redemption.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | The coupon code the operator shared. |
| dpop_token | string | – | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |

cypher_register_service Register service ~184
Register a repo as a Service node in the factory graph.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds npub. Either the grant envelope that receive_npub_proof returned, or the raw JSON of a kind-27235 Nostr event signed by npub: content "", a `u` tag holding this tool's exa… |
| npub | string | – | The patron's Nostr public key (npub1...). Tool fees are paid from this patron's balance; dpop_token proves the caller holds it. |

| repo_npub | string | yes | The service's own Nostr npub (the repo as an actor). |
No output schema declared.
No examples provided.
cypher_report_issue Report an issue ~306
File a field report about this service as a GitHub issue on the operator's repo. Found a tool's metadata or response wrong or confusing? Report it where the tool lives. The **author of record is your npub** — no npub / no proof, no issue — and it is stamped into the issue so the report is attributed to you, not the operator. Costs a small fee (a free write to an issue tracker would be abused). The report is PUBLIC and goes to the maintainers' normal triage; nothing is verified here. Returns the filed issue's repo, number, and url. If this operator has not enabled field reports, returns an "issue reporting not configured" situation and you are not charged.
| Name | Type | Req | Description |
|---|---|---|---|
| body | string | yes | The details — which tool, what was wrong, what you expected. |
| dpop_token | string | yes | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |

| tool_name | string | – | Optional: the specific tool the report is about (e.g. "schwab_get_option_chain"). |
Structured output declared, but exposes no named fields.
No examples provided.
cypher_request_adoption Request adoption ~226
Ask a chosen Authority to adopt this operator (deferred courtship). RESTRICTED to the operator — requires proof the caller controls this operator's npub. Resolves the Authority's MCP endpoint from the community registry, mints an inline ownership proof with this operator's nsec, and delivers the request MCP-to-MCP. The Authority records it as pending; its owner approves on their own time. Poll ``adoption_status`` for progress; the operator flips to ``ready`` once the Authority provisions it.
| Name | Type | Req | Description |
|---|---|---|---|
| authority_npub | string | yes | npub of the Authority to request adoption from. |
| dpop_token | string | – | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |
| note | string | – | optional message for the Authority owner. |
| service_url | string | – | this operator's MCP endpoint (advertised to the Authority). |
Structured output declared, but exposes no named fields.
No examples provided.
cypher_request_credential_channel Open credential channel ~251
Open a Secure Courier channel for credential delivery. This is the CREDENTIAL-DELIVERY flow — use it to hand over a service secret (API keys, tokens). To merely prove you control an npub (the usual answer to a ``proof_required`` error), use ``request_npub_proof`` instead. Note: dynamic/OAuth2 services (e.g. Schwab) need NO couriered secret — check ``service_status`` first. Sends a welcome DM with a credential template. The recipient must read the DM in their Nostr client, fill in the fields, and reply manually. **This is a human-in-the-loop flow.** After calling this tool, STOP and tell the user what to do. Wait for the user to confirm they have replied before calling ``receive_credentials``. Do NOT poll or retry — each ``receive_credentials`` call destructively drains the relay mailbox.
| Name | Type | Req | Description |
|---|---|---|---|
| sender_npub | string | – | Required. The npub to send the template to. |
| service | string | – | Required. The credential service name (e.g., from get_operator_onboarding_status or get_patron_onboarding_status). |
Structured output declared, but exposes no named fields.
No examples provided.
cypher_request_echo Request echo ~93
Echo what the client sent with this request. Free. Reports the URL path and query, the headers, the cookies and the MCP request ``_meta``. Values are SHA-256 fingerprints, so nothing a client sends is repeated back; equal fingerprints mean equal values. Call it from two conversations and compare: a value that stays the same within one and changes between them identifies the conversation.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
cypher_request_npub_proof Request npub proof ~502
Request npub ownership proof from a patron via Nostr DM. This is the npub-OWNERSHIP-PROOF flow — use it when a call returns ``proof_required``. It proves the caller controls an npub; it does NOT deliver any service secret. To hand an operator its API keys or OAuth secrets, use ``request_credential_channel`` instead. Sends a challenge DM that the patron must sign and reply to using their Nostr client. **This is a human-in-the-loop flow.** After calling this tool, STOP and tell the user to check their Nostr client and reply to the challenge. Wait for the user to confirm they have replied before calling ``receive_npub_proof``. Do NOT poll or retry — each ``receive_npub_proof`` call destructively drains the relay mailbox. **Returns** a ``dpop_token`` — the one-time challenge nonce shown in the DM. Pass it to ``receive_npub_proof`` to collect the reply. It is a matching token, not a credential: on its own it authorizes nothing. **Lifecycle:** ``receive_npub_proof`` returns the proof grant, which expires after the duration the patron named in their reply. When it expires, call ``request_npub_proof`` again for a fresh challenge, then wait for the user, then call ``receive_npub_proof``. Free.
| Name | Type | Req | Description |
|---|---|---|---|
| patron_npub | string | – | Required. The patron's npub to request proof from. |
| reason | string | – | Optional. A human-readable purpose for the request ("I'm working on your request XYZ and need the Operator to do ABC for you"). Signed into the provenance attestation and shown in the DM, so the reci… |

Structured output declared, but exposes no named fields.
No examples provided.
cypher_reset_pricing_model Reset pricing model ~132
Erase all pricing models and restore a viable default. Deletes every stored model, then self-initializes a fresh one from the tool registry — all tools at 0 sats with proper UUIDs. Returns the new model. RESTRICTED to operator — requires proof (nsec-signed).
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds the operator's npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by the operator whose `u` tag is this tool's name. |
Structured output declared, but exposes no named fields.
No examples provided.
cypher_restore_credits Restore credits ~256
Credit a patron's ledger from a BTCPay-settled invoice. **RESTRICTED to the operator** — the operator owns the books and is the only party who can issue a manual credit grant. Patrons who believe they paid but never got credits must escalate to the operator's support, who then invokes this tool on their behalf. Use cases: cold-start vault races during check_payment, ncred delivery hiccups, patrons closing Top-Off sheets before settle, any infrastructure incident that left an invoice settled at BTCPay but uncredited on the operator's ledger. Idempotent — if the invoice is already credited (in the patron's ``credited_invoices``), returns success with credits_granted=0.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | yes | Proof that the caller holds npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by npub whose `u` tag is this tool's name. |
| invoice_id | string | yes | The BTCPay invoice ID to verify and credit. |
| patron_npub | string | yes | The patron's npub whose ledger receives the grant. |
Structured output declared, but exposes no named fields.
No examples provided.
cypher_restore_neon_schema Restore database schema ~166
Prepare this operator's database schema again, ignoring the breadcrumb. Diagnostic / recovery tool for when Neon keeps answering 4xx and the operator suspects a table or grant is missing. Every statement is idempotent, so a clean re-run is harmless; the breadcrumb is rewritten at the end. Returns one step per concern, with Neon's own error text inline for any that failed. RESTRICTED to operator — requires proof (nsec-signed).
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds the operator's npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by the operator whose `u` tag is this tool's name. |
Structured output declared, but exposes no named fields.

| kind | string | yes | The work-item's kind: 'issue' or 'pr'. |
| npub | string | – | The patron's Nostr public key (npub1...). Tool fees are paid from this patron's balance; dpop_token proves the caller holds it. |

cypher_service_status Service status ~21
Check the health and configuration of this service. Free.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
cypher_session_status Session status ~311
Check operator readiness. Returns the operator lifecycle state and clear guidance on what to do next. Free. Lifecycle states: - ready: Vault AND pricing model verified on this call. Proceed with tool calls — this is the answer the moment the vault is up. - warming_up: Persistence could not be reached on this call (a transient failure, seen, not assumed). Retry; the next call completes the bootstrap. Never reported on a clock. - misconfigured: Persistence rejected a query with a permanent SQL error (permission denied, missing relation). Paid tools will fail until the operator repairs the database — retrying does not help. - quota_exceeded: The persistence provider (Neon) answered HTTP 402 — the operator's database has exhausted its compute/storage quota, so the books are locked for billing. Paid tools fail; retrying does NOT help. The operator's Authority must restore capacity (upgrade the plan or wait for the quota reset). Free tools remain available. - not_registered: Operator has no Authority relationship yet. Call register_operator first. - no_identity: Operator nsec is not configured. Deployment issue.
| Name | Type | Req | Description |

cypher_set_pricing_model Set pricing model ~135
Set the active pricing model. RESTRICTED to operator. Requires a valid proof (Schnorr-signed kind-27235 event) proving the caller holds the operator's nsec.
| Name | Type | Req | Description |
|---|---|---|---|
| dpop_token | string | – | Proof that the caller holds the operator's npub: the grant envelope from receive_npub_proof, or the raw JSON of a kind-27235 Nostr event signed by the operator whose `u` tag is this tool's name. |
| model_json | string | yes | The complete pricing model as a JSON object; it replaces the active model. |
Structured output declared, but exposes no named fields.
No examples provided.
