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.

cypher_check_authority_balance Authority balance ~73
Check this operator's tax balance at the Authority. Returns the sats available for certifying patron credit purchases. When this balance reaches zero, patron top-ups cannot be certified and the operator must call purchase_credits on the Authority. This is the operator's own funding — not a patron balance. Free.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
cypher_check_balance Check balance ~167
Check a patron's credit balance at this operator. This is the patron's spending balance — credits purchased via Lightning for tool calls at this operator. For the operator's own balance at the Authority (needed to certify patron purchases), use authority_check_balance instead. Free — no credits required. Proof of npub ownership is required to prevent anyone-with-the-registry from enumerating balances.
| 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. |

| tool_kwargs | string | – | Optional JSON object with tool call parameters for ad valorem / categorical-multiplier pricing preview (e.g. '{"amount_sats": 5000}' or '{"difficulty": "sovereign", "mode": "live"}'). |
Structured output declared, but exposes no named fields.
No examples provided.
cypher_check_proof_status Check proof status ~172
Check whether a proof grant is still valid. Mirrors ``check_oauth_status`` for the npub-proof flow: a calling agent can ask "will my next paid call accept this dpop_token?" before burning credits on a guaranteed failure. Expiry is read from the grant itself; the only store consulted is the patron's revocation watermark. Free, no side effects — touches no relay.
| 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. |

Structured output declared, but exposes no named fields.
No examples provided.
cypher_delete_coupon Delete coupon ~146
Delete a coupon. Cascades to all patron redemptions. Any chain step referencing the deleted coupon_id becomes a no-op (the constraint returns neutral on unknown ids) — the Studio surfaces orphan references as warnings. RESTRICTED to operator — requires proof.
| Name | Type | Req | Description |
|---|---|---|---|
| coupon_id | string | yes | The id of the coupon to delete (from list_coupons). |
| 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_delete_operator_credential Delete operator credential ~266
Remove a single operator secret field. Deletes one key from the operator's encrypted credential blob without touching the others — the field-level counterpart to ``forget_credentials``, which wipes the whole row. Use it to retire a leftover after an SDK cutover (a Prefect key after Modal, or a stored but untemplated orphan like ``anthropic_api_key``) without taking the operator down for a full re-delivery. Stored-but-untemplated fields are first-class: the delete is keyed on what is vaulted, not on what the current template declares. Idempotent — already-absent fields report ``removed: false`` without rewriting the vault. RESTRICTED to the operator — requires the operator's proof (a kind-27235 event or a proof grant); patron proofs are rejected. A deletion is as destructive as a write.
| 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. |

| 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. |

Structured output declared, but exposes no named fields.
No examples provided.
cypher_execute_query_by_key Run a query by key ~302
Execute a published, parameterized Cypher query by its key. You supply the key of an operator-published query plus its parameters. The operator owns the query text; you never see or write raw Cypher. If the operator has published a query as a named tool (e.g. ``cypher_which_service_handles``), you can call that directly instead. Billing note: you are charged only for a delivered answer. If the key is unknown, the parameters are invalid, or the query fails, the call raises and your debit is rolled back (no charge for value not delivered).
| 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… |

cypher_forget_coupon Forget coupon ~163
Remove a coupon from this patron's redemption list. Cosmetic only — the coupon itself still exists at the operator, and the patron can re-redeem the same code later while the window allows. Free — requires proof of ``npub``.
| Name | Type | Req | Description |
|---|---|---|---|
| coupon_id | string | yes | The id of the redeemed coupon to remove (from list_my_coupons). |

No examples provided.
cypher_forget_credentials Forget credentials ~154
Delete vaulted credentials for a specific service and npub. For operator credentials, pass the operator's own npub. For patron credentials, pass the patron's npub. Always requires proof of npub ownership — a deletion is as destructive as a write.
| Name | Type | Req | Description |
|---|---|---|---|

Structured output declared, but exposes no named fields.
No examples provided.
cypher_get_nostr_profile Nostr profile ~102
Read an npub's public Nostr profile (NIP-01 kind-0 metadata). Free, no proof — the data is already public on relays. Returns the latest metadata fields (name, display_name, about, picture, banner, nip05, website, lud16) or an empty profile if none is published.
| Name | Type | Req | Description |
|---|---|---|---|
| npub | string | – | The Nostr public key (npub1...) whose profile to read. |

For dynamic/OAuth2 services (Schwab), reports that no patron credentials are needed. Free. Proof of npub ownership is required because credential presence is sensitive information about the patron's setup.
| 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. |

cypher_get_query Get a query ~248
Operator-only: fetch one catalog entry (template + schema + metadata). Includes ``edit_url`` — a one-click deep link into the hosted Neo4j Browser that pre-targets this operator's AuraDB and loads the template in EDIT mode, so the analyst refines it in Neo4j's own UI and saves it back with ``update_query``. Omitted if the operator's Neo4j credentials aren't delivered yet (best-effort; the raw template is always present to paste).
