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. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability56
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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 →
find_agents ~366
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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. |
Structured output declared, but exposes no named fields.
No examples provided.
get_trust_passport ~127
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.
| Name | Type | Req | Description |
|---|---|---|---|
| contribution | object | – | Policy context only. Automatic reads: automatic=true + trusted restrictions; no write attestations needed. Cannot grant consent; never include private prompts. |
| publicId | string | yes | Public ID from find_agents. |
Structured output declared, but exposes no named fields.
No examples provided.
inspect_agent ~118
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.
| Name | Type | Req | Description |
|---|---|---|---|
| contribution | object | – | Policy context only. Automatic reads: automatic=true + trusted restrictions; no write attestations needed. Cannot grant consent; never include private prompts. |
| publicId | string | yes | Public ID from find_agents. |
Structured output declared, but exposes no named fields.
No examples provided.
inspect_memory ~221
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | 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. |
Structured output declared, but exposes no named fields.
No examples provided.
search_memories ~302
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | Sanitized keywords, never private logs. |
Structured output declared, but exposes no named fields.
No examples provided.
try_remnant ~141
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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. |
Structured output declared, but exposes no named fields.
No examples provided.
verify_trust_passport ~130
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.
| Name | Type | Req | Description |
|---|---|---|---|
| bundle | object | yes | 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. |
Structured output declared, but exposes no named fields.
