Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →

Supply Chain Security87
  • No malware found by supply-chain analysis.Pass
  • Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.Partial
  • No install/post-install scripts declared.Pass
  • Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency45
Schema Quality & AI Usability40
  • AI-judged instruction clarity (poor).Fail
  • Context-footprint check failed: tool/resource definitions use about 1320 tokens (~120/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
  • Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage86
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 50% of tool parameters carry a description.Partial
  • Structured output schemas are declared (9% of tools); any adoption earns full credit.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Changelog

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

  • 3 Aug 26 +1

    No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

MCP tools — 11 exposed · ~1,196 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.

Tool Tokens
anchor_artifact ~185

Prove an artifact existed exactly as-is at this moment, and make any later tampering detectable. Give a file `path` (hashed locally with SHA-256 — the file itself is NEVER uploaded) or a precomputed `sha256`. The hash is registered on Fidacy's tamper-evident audit chain, which is checkpointed to the Bitcoin blockchain, and you get a signed receipt (JWS) verifiable offline against the engine JWKS. Use it for contracts, invoices, medical prescriptions, insurance claims, images, audio, video. `kind` defaults to document; optional `label` is a short reference (an invoice number, a case id — no PII).

No output schema declared.

No examples provided.

assess_action ~195

Return a SIGNED Fidacy trust verdict from the live engine (default https://api.fidacy.com) for a proposed action. The signed proof is `riskPayloadJws` + `signingKeyId`, verifiable by anyone via @fidacy/verify against the engine JWKS at /.well-known/jwks.json. `kind` is one of ap2_payment, message_send, voice_call, custom, claim_document; `mandate` is the action/mandate object for that kind. This is the verdict (advisory) layer and moves no money; it complements the payment-firewall tools (request_payment et al.) in the same install.

check_artifact ~94

Check whether an artifact was anchored by this account and the state of its Bitcoin checkpoint. Give a file `path` (hashed locally, never uploaded) or a `sha256`. If the current hash of a file does NOT match any anchored record that you expected to match, the file changed since anchoring — that is exactly the tampering signal.

NameTypeReqDescription
pathstring
sha256string

No output schema declared.

No examples provided.

explain_decision ~72

Explain one decision in plain language: what was requested, what the mandate did about it, why, and the tamper-evident proof for it. Use when an operator asks why a specific payment was blocked.

NameTypeReqDescription
decisionIdstringyesDecision id from request_payment, list_decisions or spend_summary

No output schema declared.

No examples provided.

get_audit_proof ~56

Return the tamper-evident, hash-chained proof for a decision id, including whether the chain is intact and the public key it verifies against.

NameTypeReqDescription
decisionIdstringyesDecision id returned by request_payment

No output schema declared.

No examples provided.

list_decisions ~87

List recent agent payment decisions, newest first, with payee, amount, the agent's stated reason, and for blocked ones the rule that stopped it. Filter by status to answer 'what got blocked' directly. Read-only, works offline.

NameTypeReqDescription
limitintegerHow many decisions to return. Default 20.
statusstringFilter by outcome. Default all.

No output schema declared.

No examples provided.

request_payment ~222

Authorize a payment action against the active Fidacy mandate. Returns an ALLOW with a signed grant, or a DENY with the violated rule. The downstream executor MUST require the grant. Call this before any payment; never pay without it.

sentinel_alerts ~98

Predictive pattern alerts from the local audit chain: first-ever payee, amount spikes vs this agent's own history, velocity bursts, payments riding the mandate ceiling, and retries after a denial (the behavior our Model Watch benchmark measures). Deterministic and explainable, no model. Use to answer 'has anything unusual happened' before it becomes a loss.

NameTypeReqDescription
limitintegerHow many flagged decisions to return. Default 20.

No output schema declared.

No examples provided.

spend_summary ~97

Operator report over a time window: how many payment decisions were made, how much was paid and to whom, how much was blocked before executing, and which mandate rules did the blocking. Read-only, works offline against the local audit chain. Use this to answer questions like 'what did my agents spend this week' or 'has anything been blocked'.

NameTypeReqDescription
daysintegerWindow in days, counting back from now. Default 7.

No output schema declared.

No examples provided.

upgrade ~49

Start upgrading this local install to a real Fidacy account (server-backed signed verdicts, anchored proof, higher volume). Returns a link to open; your anonymous usage is preserved and migrated to the new account.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

verify_mandate ~41

Return the active mandate envelope (caps, allowed payees/categories, window, revocation) and Fidacy's Ed25519 public key for grant verification.

Input schema present but exposes no named parameters.

No output schema declared.
