84 tools

• brain_check_balance

  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…

• brain_purchase_credits

  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.

• brain_check_payment

  Check the payment status of a Lightning invoice. Call after paying the invoice from purchase_credits. Free — no credits required. Proof of npub ownership is required to prevent credit-grant front-running by an observer of the invoice ID.

• brain_restore_credits

  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…

• brain_account_statement

  Generate a patron's account statement at this operator. Returns the patron's purchase history, active credit tranches, per-tool usage breakdown, and recent daily usage logs. This is the patron's spending account — not the operator's Authority tax balance. Free — no credits…

• brain_account_statement_infographic

  Generate a visual SVG infographic of your account statement. Returns the same data as account_statement, rendered as a dark-themed SVG graphic with balance hero, metrics cards, health gauge, tranche table, and tool usage breakdown. Costs 1 api_sat per call. Proof is verified by…

• brain_report_issue

  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…

• brain_service_status

  Check the health and configuration of this service. Free.

• brain_request_echo

  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…

• brain_get_operator_onboarding_status

  Report this operator's configuration readiness. Shows which operator settings are configured, which are missing, and how to deliver each missing value. For patron-level credential status, use get_patron_onboarding_status instead. Free.

• brain_get_patron_onboarding_status

  Report a patron's credential readiness for this operator. For set-once services (eXcalibur, TheBrain), shows which patron secrets are configured and which are missing. For dynamic/OAuth2 services (Schwab), reports that no patron credentials are needed. Free. Proof of npub…

• brain_session_status

  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…

• brain_request_credential_channel

  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…

• brain_receive_credentials

  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…

• brain_forget_credentials

  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.

• brain_request_patron_credentials

  Open a Secure Courier channel for patron credential delivery. Sends a welcome DM with a credential template to the patron. Free.

• brain_receive_patron_credentials

  Pick up patron credentials from the Secure Courier. Deterministic, one-shot retrieval: name the response with ``(sender_npub, dpop_token)`` and the tool drains ONLY the pinned rendezvous relay for that channel, stopping at the matching DM. Provide an ncred1... credential_card…

• brain_update_patron_credential

  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…

• brain_update_operator_credential

  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…

• brain_delete_patron_credential

  Remove a single patron credential field. Deletes one field from stored credentials without affecting other fields. Free. Proof of npub ownership is required — this is a write to the patron's sensitive credential vault.

• brain_delete_operator_credential

  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…

• brain_get_patron_credential_fields

  List stored patron credential field names (not values). Returns the names of fields stored for a patron, plus each field's ``delivered_at`` ISO-8601 timestamp when known (null for secrets vaulted before timestamps were recorded). Values are never exposed — use this to verify…

• brain_request_npub_proof

  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…

• brain_receive_npub_proof

  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…

• brain_check_proof_status

  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…

• brain_oracle_how_to_join

  Get DPYC onboarding instructions from the Oracle. Free.

• brain_oracle_get_tax_rate

  Get the current DPYC certification tax rate. Free.

• brain_oracle_lookup_member

  Look up a DPYC community member by npub. Free.

• brain_oracle_about

  Describe the DPYC ecosystem via the Oracle. Free.

• brain_oracle_network_advisory

  Get active network advisories from the Oracle. Free.

• brain_check_authority_balance

  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…

• brain_get_pricing_model

  Get the active pricing model for this operator. Free. If no model exists, self-initializes a scaffold with all registered tools at 0 sats. No economic data from code.

• brain_set_pricing_model

  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.

• brain_reset_pricing_model

  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).

• brain_request_adoption

  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…

• brain_adoption_status

  Check this operator's adoption-request status at a chosen Authority. Free. Polls the Authority MCP-to-MCP for the status of this operator's request (pending / approved / rejected / provisioned).

• brain_restore_neon_schema

  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…

• brain_list_canonical_identities

  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…

• brain_get_nostr_profile

  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.

• brain_publish_nostr_profile

  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…
