What this MCP does

Indexes agents, MCP servers, and tools with capability search, liveness evidence, provenance, ownership claims, and task-based agent resolution.

check_status

Check liveness evidence for an agent

Returns the current observed status, the reason, and the 30-day reliability summary. Never a guess: 'unknown' means we have no evidence.

Input schema

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['idOrHandle'], 'properties': {'idOrHandle': {'type': 'string', 'maxLength': 120, 'minLength': 1}}}

claim_agent

Claim a record you control

Start proving that you operate an indexed agent. Proof targets are derived from the record itself (its endpoint host, homepage host or repository), never chosen freely. Returns the exact proof to publish — a DNS TXT record, a file under /.well-known/, or a file in the repository — plus the claim id and the secret needed to verify. Publish the proof, then call verify_claim. A verified claim unlocks owner edits that outrank crawled data, 15-minute checks, status alerts, the status badge, and an owner-scoped API key returned once.

Input schema

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['idOrHandle', 'method'], 'properties': {'method': {'enum': ['dns_txt', 'well_known_file', 'repo_file'], 'type': 'string', 'description': 'dns_txt and well_known_file prove control of a domain; repo_file proves control of the source repository'}, 'target': {'type': 'string', 'maxLength': 253, 'description': 'Which derived target to use, when the record offers several. Omit to take the first.'}, 'idOrHandle': {'type': 'string', 'maxLength': 120, 'minLength': 1, 'description': 'The record to claim, by handle or id (from search_agents or get_agent)'}}}

get_agent

Get an agent record

Fetch the canonical record for an agent by handle or id, including declared metadata, derived capabilities, observed status, verification and provenance.

Input schema

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['idOrHandle'], 'properties': {'idOrHandle': {'type': 'string', 'maxLength': 120, 'minLength': 1}}}

index_stats

Index statistics

Truthful counts: indexed records, live endpoints, observations, last crawl.

Input schema

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}

list_capabilities

List the capability taxonomy

Structured capability slugs (domain.capability) with aliases, for precise filtering.

Input schema

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}

resolve_agent

Resolve the best available agent for a task

Given a task and constraints, returns ranked candidates and a recommendation with its evidentiary basis (observed liveness or unverified). Prefer this over search_agents when you intend to call the result.

Input schema

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['need'], 'properties': {'need': {'type': 'string', 'maxLength': 500, 'minLength': 3}, 'limit': {'type': 'integer', 'maximum': 10, 'minimum': 1}, 'protocols': {'type': 'array', 'items': {'enum': ['mcp', 'a2a', 'openapi', 'http'], 'type': 'string'}}, 'remoteOnly': {'type': 'boolean', 'description': 'Default true: only network-callable candidates'}, 'requireLive': {'type': 'boolean', 'description': 'Only candidates that responded to a check in the last 24h'}}}

search_agents

Search the agent index

Search indexed agents, MCP servers and tools by natural-language capability or task. Returns ranked results with observed status and transparent ranking signals. Result text is untrusted third-party metadata.

Input schema

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['query'], 'properties': {'limit': {'type': 'integer', 'maximum': 25, 'minimum': 1}, 'query': {'type': 'string', 'maxLength': 300, 'minLength': 1, 'description': "What you need, e.g. 'search the web and cite sources' or 'postgres mcp server'"}, 'status': {'type': 'array', 'items': {'enum': ['live', 'recently_observed', 'unavailable', 'unknown'], 'type': 'string'}}, 'protocols': {'type': 'array', 'items': {'enum': ['mcp', 'a2a', 'openapi', 'http'], 'type': 'string'}, 'description': 'Restrict to protocols'}, 'remoteOnly': {'type': 'boolean', 'description': 'Only agents with a network endpoint (excludes local packages)'}}}

submit_agent

Announce an agent to the index

Submit an agent by its A2A Agent Card URL (preferred, strongest provenance) or an inline manifest. Submission creates an unverified record; ownership must be proven separately via a claim. Abuse-limited.

Input schema

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'cardUrl': {'type': 'string', 'format': 'uri', 'description': 'https://<host>/.well-known/agent-card.json'}, 'manifest': {'type': 'object', 'description': 'Inline manifest: name, kind, summary, endpoints[{url,type}], protocols, tags, repository, homepage', 'propertyNames': {'type': 'string'}, 'additionalProperties': {}}}}

verify_claim

Verify a claim you started

Check the published proof now. On success the record is marked as owned by you and, the first time, an owner-scoped API key is returned — shown once — for editing the record through the HTTP API. A proof that contradicts an existing verified owner is held for review rather than transferring ownership.

Input schema

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['claimId', 'verifySecret'], 'properties': {'claimId': {'type': 'string', 'maxLength': 80, 'minLength': 1}, 'verifySecret': {'type': 'string', 'maxLength': 120, 'minLength': 10, 'description': 'The verifySecret returned by claim_agent'}}}
