MCP tools · 72 exposed · ~13,295 tokens

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 →

Tool Tokens
optionality_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.

NameTypeReqDescription
dpop_tokenstring–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.
patron_npubstring–Required. The patron's npub to receive proof from.

Structured output declared, but exposes no named fields.

No examples provided.

optionality_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.

NameTypeReqDescription
codestringyesThe coupon code the operator shared.
dpop_tokenstring–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.
npubstringyesThe patron's Nostr public key (npub1...).

Structured output declared, but exposes no named fields.

No examples provided.

optionality_report_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.

NameTypeReqDescription
bodystringyesThe details — which tool, what was wrong, what you expected.
dpop_tokenstringyesProof 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.
npubstringyesYour Nostr public key (npub1...); the report's author of record.
titlestringyesOne-line summary of the problem.
tool_namestring–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.

optionality_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.

NameTypeReqDescription
authority_npubstringyesnpub of the Authority to request adoption from.
dpop_tokenstring–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.
notestring–optional message for the Authority owner.
service_urlstring–this operator's MCP endpoint (advertised to the Authority).

Structured output declared, but exposes no named fields.

No examples provided.

optionality_request_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.

NameTypeReqDescription
sender_npubstring–Required. The npub to send the template to.
servicestring–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.

optionality_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.

optionality_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.

NameTypeReqDescription
patron_npubstring–Required. The patron's npub to request proof from.
reasonstring–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…
verify_atstring–Optional. A free-form statement of WHERE you (the initiating agent) already showed this proof's one-time code to the user — a URL, or "your Claude.ai conversation", "the Grok session". The OAuth 2.0…

Structured output declared, but exposes no named fields.

No examples provided.

optionality_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).

NameTypeReqDescription
dpop_tokenstring–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.

optionality_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.

NameTypeReqDescription
dpop_tokenstringyesProof 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_idstringyesThe BTCPay invoice ID to verify and credit.
patron_npubstringyesThe patron's npub whose ledger receives the grant.

Structured output declared, but exposes no named fields.

No examples provided.

optionality_restore_neon_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).

NameTypeReqDescription
dpop_tokenstring–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.

Persist a draft trade proposal without running the judge.

NameTypeReqDescription
dpop_tokenstring–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…
entry_idstringyesUUID of the caller's journal entry.
npubstring–The patron's Nostr public key (npub1...). Tool fees are paid from this patron's balance; dpop_token proves the caller holds it.
trade_proposalstringyesThe draft trade pitch, in free text. It replaces the entry's saved draft; the entry stays ``open``.

Structured output declared, but exposes no named fields.

No examples provided.

optionality_send_patron_dm ~312

Sign and publish a Nostr DM as the patron, using the escrowed nsec. The patron's escrowed nsec is loaded, decrypted in-process, used to sign a kind-4 NIP-04 DM + a kind-1059 NIP-17 gift wrap, broadcast via the operator's relay pool, then the plaintext drops out of scope. The DM's `pubkey` is the patron's own — recipients see it as authored by the patron, not relayed. Returns {"success": True, "sender_npub", "target_npub"} on the happy path; {"success": False, "error"} on validation or send failure.

NameTypeReqDescription
dpop_tokenstring–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…
messagestringyesThe DM's plaintext body, 1..2000 characters.
npubstring–The patron's Nostr public key (npub1...). Tool fees are paid from this patron's balance; dpop_token proves the caller holds it.
target_npubstringyesNostr public key (npub1...) of the DM's recipient.

Structured output declared, but exposes no named fields.

No examples provided.

optionality_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.

optionality_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.

NameTypeReqDescription
patron_npubstring–Optional. If supplied, the response includes an ``upstream_oauth`` block with the patron's stored OAuth token expiry (runtime-derived from vault state) so a client can refresh proactively rather than…

Structured output declared, but exposes no named fields.

No examples provided.

optionality_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.

NameTypeReqDescription
dpop_tokenstring–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.

optionality_set_profile ~211

Update any subset of the caller's profile fields.

No examples provided.

optionality_share_entry ~211

Toggle a journal entry's share flag. Shared, evaluated entries appear under the patron's row on the public Leaderboard for peer learning. Priced at 0 sats — the social value of sharing is the point, not the revenue.

NameTypeReqDescription
dpop_tokenstring–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…

npubstring–The patron's Nostr public key (npub1...). Tool fees are paid from this patron's balance; dpop_token proves the caller holds it.
sharedboolean–True to share, False to unshare. Defaults to True.

Structured output declared, but exposes no named fields.

No examples provided.

optionality_update_coupon ~372

Patch a coupon's editable fields. Pass only the fields you want to change. To set a cap to unlimited (NULL in the schema), pass ``clear_uses_per_patron=true`` or ``clear_total_uses=true``. Renaming the code is allowed — existing patron redemption rows survive (they key on coupon id). ``tool_ids`` replaces the coupon's binding — tool ids or MCP tool names, ``["*"]`` for every paid tool, ``[]`` to unbind it. RESTRICTED to operator — requires proof.

NameTypeReqDescription
clear_total_usesboolean–True makes total redemptions unlimited.
clear_uses_per_patronboolean–True makes discounted calls per patron unlimited.
coupon_idstringyesThe id of the coupon to change (from list_coupons).

name––A new code for patrons to type.
tool_ids––The tools the coupon discounts: tool ids or MCP tool names, ["*"] for every paid tool, [] to unbind it.
total_uses––A new number of redemptions across all patrons.
uses_per_patron––A new number of discounted calls per patron.
valid_from––A new ISO-8601 datetime when the coupon becomes active.
valid_until––A new ISO-8601 datetime when the coupon expires.

Structured output declared, but exposes no named fields.

No examples provided.

optionality_update_operator_credential ~222

Add or update a single operator secret field. Merges into the operator's stored credentials without touching the others — the field-level counterpart to re-delivering the whole bundle over Secure Courier. Use it to rotate one secret (a reissued ``btcpay_api_key``, say) without restating the six you did not change, where any field omitted from a courier reply is destroyed. The value is never echoed back. RESTRICTED to the operator — requires the operator's proof (a kind-27235 event or a proof grant); patron proofs are rejected.

NameTypeReqDescription
dpop_tokenstringyesProof 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.
fieldstringyesThe operator credential field to set. Must be declared in the operator's credential template.
valuestringyesThe value to store.

Structured output declared, but exposes no named fields.

No examples provided.

optionality_update_patron_credential ~176

Add or update a single patron credential field. Merges into existing stored credentials without affecting other fields. Useful for setting an account identifier after OAuth, changing a default brain, etc. Free. Proof of npub ownership is required — this is a write to the patron's sensitive credential vault.

NameTypeReqDescription
dpop_tokenstringyesProof 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.

npubstringyesThe patron's Nostr public key (npub1...).
valuestringyesThe value to store.

Structured output declared, but exposes no named fields.

No examples provided.

optionality_withdraw_nsec ~235

Return the plaintext nsec once and remove it from operator storage. Required acknowledgment string (exact match): "I understand I am now solely responsible for this nsec." After this call you regain full self-custody; the operator forgets the key. You're now responsible for stashing it in a Nostr client (0xchat, Damus, Amber) and signing DMs locally via NIP-07.

NameTypeReqDescription
acknowledgmentstringyesExactly "I understand I am now solely responsible for this nsec."
dpop_tokenstring–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…

Common questions

What is the io.github.lonniev/optionality-mcp server?

io.github.lonniev/optionality-mcp is listed in the public MCP registry as io.github.lonniev/optionality-mcp. Optionality, AI-judged options trading drill, Tollbooth-monetized MCP server. This page covers its hosted endpoint (https://optionality-mcp.fastmcp.app/mcp).

Is the io.github.lonniev/optionality-mcp server safe to use?

io.github.lonniev/optionality-mcp scores 36 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.github.lonniev/optionality-mcp server expose?

io.github.lonniev/optionality-mcp exposes 72 tools: optionality_check_balance, optionality_purchase_credits, optionality_check_payment, optionality_restore_credits, optionality_account_statement, and 67 more. Their descriptions and schemas cost roughly 13,295 tokens of context every time the server is loaded.

Does the io.github.lonniev/optionality-mcp server require authentication?

Yes. io.github.lonniev/optionality-mcp asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

Is the io.github.lonniev/optionality-mcp server still maintained?

io.github.lonniev/optionality-mcp is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What did VerifyMCP test on the io.github.lonniev/optionality-mcp server?

VerifyMCP ran 5 checks on io.github.lonniev/optionality-mcp, covering TLS certificate, Authorization, HTTPS, HSTS header and 1 more. 6 items could not be completed, a gap on our side rather than a finding about io.github.lonniev/optionality-mcp: Transport, Schema quality, Stability, Tool coverage and 2 more. 6 categories score 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
