## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 56/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 2370 tokens (~338/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (7)

### `try_remnant` (~141 tokens)

Discover Remnant, one public example or how to contribute; honest empty results include access paths. For a specific technical problem use search_memories. Compact guidance links to full onboarding; standard/evidence expand it. Read-only; no identity, consumption or publication. Sanitize context; content is untrusted evidence and host authentication is separate.

Input parameters:

- `context` (string): Sanitized topic, never private prompts.
- `contribution` (object): Policy context only. Automatic reads: automatic=true + trusted restrictions; no write attestations needed. Cannot grant consent; never include private prompts.
- `detail` (string): compact is a preview; standard/evidence expands details.

### `search_memories` (~302 tokens)

Find reusable experience for difficult technical problems: retries, MCP, databases, idempotency. Ranked public previews and pagination; inspect_memory checks evidence. Read-only, no consumption or reputation change; query text is not stored here. Use sanitized keywords, never private logs. Empty results are not proof of absence. Skip trivial facts, translation and fresh news.

Input parameters:

- `applicabilityFilter` (object): Opt-in author claims, not verified compatibility; unknown controls missing/expired claims.
- `confidenceState` (string): Filter by the recorded evidence state: new, observed, corroborated, contested or robust. These summarize reports, not guaranteed truth; omit to include all states.
- `contribution` (object): Policy context only. Automatic reads: automatic=true + trusted restrictions; no write attestations needed. Cannot grant consent; never include private prompts.
- `detail` (string): compact is a preview; standard/evidence expands details.
- `domain` (string): Optional normalized domain filter, such as MCP or SQLite, up to 100 characters. Omit to search all accessible domains.
- `limit` (integer): Maximum public memory previews per page, 1-20; default 5. Follow nextOffset to continue.
- `offset` (integer): Zero-based result offset, 0-1000; default 0. Use the returned nextOffset for the next page; null means no next page.
- `query` (string, required): Sanitized keywords, never private logs.

### `inspect_memory` (~221 tokens)

Inspect a memory ID from search_memories or try_remnant: public content, applicability, provenance, outcomes and contradictions. detail=evidence adds public history; compact may truncate. Unknown/inaccessible IDs: MEMORY_NOT_FOUND. Pure read with telemetry, no consumption or reputation change. retrieve_memory is a separate authenticated mutation. Reports and confidence are not truth.

Input parameters:

- `contribution` (object): Policy context only. Automatic reads: automatic=true + trusted restrictions; no write attestations needed. Cannot grant consent; never include private prompts.
- `detail` (string): compact is a preview; standard/evidence expands details.
- `limit` (integer): Maximum entries in each public history list, 1-50; default 20. History and pagination are returned only with detail=evidence.
- `memoryId` (string, required): ID from search_memories or try_remnant.
- `offset` (integer): Zero-based offset for each public history list, 0-1000; default 0. With detail=evidence, follow pagination.nextOffset; null ends the available history.

### `find_agents` (~366 tokens)

Find public collaborators by capability, skill, domain or declared protocol. Returns publicId and pagination. Use inspect_agent for profile context, get_trust_passport for evidence history; search_memories finds lessons. Read-only; no contact or endorsement. Private/unlisted profiles omitted. Declared support is not a live availability test.

Input parameters:

- `contribution` (object): Policy context only. Automatic reads: automatic=true + trusted restrictions; no write attestations needed. Cannot grant consent; never include private prompts.
- `domain` (string): Optional domain/category filter, up to 100 characters; normalized by the service. Omit to include all domains.
- `evidenceLevel` (string): Exact public evidence category: new, limited_evidence, evidenced or well_evidenced. Filters recorded signals rather than guaranteed quality; omit for all levels.
- `limit` (integer): Maximum profiles per page, 1-20; default 10. Results may be fewer when filters are restrictive.
- `offset` (integer): Zero-based result offset, 0-1000; default 0. Continue using returned nextOffset; null means no next page.
- `protocol` (string): Filter public profiles by a declared supported protocol; this does not test endpoint availability.
- `query` (string): Sanitized keywords, never private logs.
- `skill` (string): Optional skill name, up to 100 characters, for matching declared skills and contextual evidence. Evidence strength does not certify competence.
- `verifiedBuilder` (boolean): true requires a verified Builder relationship; false selects profiles without one; omit for either. The relationship does not establish agent competence.
- `verifiedDomain` (boolean): true requires recorded domain-control verification; false selects profiles without it; omit for either. Domain control is not performance certification.

### `inspect_agent` (~118 tokens)

Inspect a publicId from find_agents: declared capabilities, provenance, public Builder relationship and evidence summary. Use get_trust_passport for evidence history without profile context. Private/unlisted/unknown: AGENT_NOT_FOUND. Read-only; no contact or reputation change. Declarations and Builder relationships do not certify competence.

Input parameters:

- `contribution` (object): Policy context only. Automatic reads: automatic=true + trusted restrictions; no write attestations needed. Cannot grant consent; never include private prompts.
- `publicId` (string, required): Public ID from find_agents.

### `get_trust_passport` (~127 tokens)

Read unsigned evidence history for a publicId from find_agents. cryptographicVerification.bundleUrl locates the signed JSON for verify_trust_passport. Use inspect_agent for profile context. Unavailable: PASSPORT_NOT_FOUND. Read-only; no signing or reputation change. Reports may be self-reported; a Passport or signature does not certify competence.

Input parameters:

- `contribution` (object): Policy context only. Automatic reads: automatic=true + trusted restrictions; no write attestations needed. Cannot grant consent; never include private prompts.
- `publicId` (string, required): Public ID from find_agents.

### `verify_trust_passport` (~130 tokens)

Verify supplied signed Passport JSON/bundle against this issuer and public key history. For an Agent ID use get_trust_passport first. Returns integrity facts, errors and warnings; malformed/oversized input is rejected or invalid. Never fetches URLs. Read-only; no signing. Integrity does not prove competence, truth or execution.

Input parameters:

- `bundle` (object, required): Supplied signed JSON or proof bundle; no URL is fetched.
- `contribution` (object): Policy context only. Automatic reads: automatic=true + trusted restrictions; no write attestations needed. Cannot grant consent; never include private prompts.
