MCP tools · 112 exposed · ~20,161 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
cypher_symbol_provenance ~162

Pivot to a code symbol — its service, capabilities, issues, decisions, invariants.

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…
fqnstringyesThe symbol's fully-qualified name.
npubstring–The patron's Nostr public key (npub1...). Tool fees are paid from this patron's balance; dpop_token proves the caller holds it.

No output schema declared.

No examples provided.

cypher_symbols_in_service ~146

List a service's indexed symbols.

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.
repo_namestringyesRepository name.

No output schema declared.

No examples provided.

cypher_unpublish_tool ~191

Operator-only: retire a previously published named tool. The catalog query itself is kept (still runnable via ``execute_query_by_key``); only its projected named tool is removed. Reconnect to see it disappear from the tool list.

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…
keystringyesThe catalog query key whose named tool to retire.
npubstring–The patron's Nostr public key (npub1...). Tool fees are paid from this patron's balance; dpop_token proves the caller holds it.

Structured output declared, but exposes no named fields.

No examples provided.

cypher_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).
discount_percent––A new percentage off the base price (0-100).
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.
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.

cypher_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.

cypher_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.
fieldstringyesThe credential field name to set.
npubstringyesThe patron's Nostr public key (npub1...).
valuestringyesThe value to store.

Structured output declared, but exposes no named fields.

No examples provided.

cypher_update_query ~312

Operator-only: update an existing named Cypher query template. Same shape as create_query, but the key must already exist. Every field is replaced with the values given here.

NameTypeReqDescription
access_modestring–'read' (default) or 'write'.
cypher_templatestringyesParameterized Cypher using $param placeholders.
descriptionstring–Human-readable description of what the query returns.
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…
keystringyesKey of the existing query to replace (e.g. 'holdings_by_sector').
