Tool name: search_discoverable_registry_records

Description:
Searches for approved registry records using natural language queries. Returns metadata for matching records.

Parameters:
- searchQuery (required): string - Natural language search query
- maxResults: integer - Maximum number of results to return (1-20, default 10)
- filter: object - Optional metadata filter using structured JSON operators. Supports field-level operators ($eq, $ne,
  $in) and logical operators ($and, $or) on filterable fields (name, recordType, recordVersion). Example:
  {"recordType": {"$eq": "MCP"}}

---

Tool name: list_discoverable_registry_records

Description:
Returns paginated summaries of approved records in the registry. Summaries include record metadata but not descriptor
content. Use batch_get_discoverable_registry_record to fetch full descriptors after identifying the records you need.

Parameters:
- maxResults: integer - Maximum number of results per page (1-100, default 20)
- nextToken: string - Pagination token from a previous response. Omit for the first page.
- filters: array - Optional list of filter entries in the form {"name": "<field>", "values": ["<value>"]}. Supported
  filter names: recordType (valid values: AGENT, MCP, SKILL, CUSTOM) and descriptorType (valid values: a2aAgentCard,
  mcpServer, agentSkillsDefinition, custom). Duplicate filter names are rejected. If you specify multiple values for
  a single filter, the values are joined by OR. If you specify multiple filters, the filters are joined by AND.

---

Tool name: batch_get_discoverable_registry_record

Description:
Retrieves the full descriptor content for up to 100 approved records in a single call. Common use case: after
identifying records with list_discoverable_registry_records or search_discoverable_registry_records, fetch their full
descriptors in one call rather than making one call per record.

Parameters:
- recordIds (required): array - List of 1-100 record ARNs or IDs to retrieve from the registry.

The response returns HTTP 200 even on partial failure. Records that could not be retrieved appear in an errors list
with an errorCode (RESOURCE_NOT_FOUND, ACCESS_DENIED, or INTERNAL_ERROR) rather than causing the whole call to fail.

Tool name: search_registry_records

Description:
Searches for registry records using natural language queries. Returns metadata for matching records.

Parameters:
- searchQuery (required): string - Natural language search query
- maxResults: integer - Maximum number of results to return (1-20, default 10)
- filter: object - Optional metadata filter using structured JSON operators. Supports field-level operators ($eq, $ne,
  $in) and logical operators ($and, $or) on filterable fields (name, descriptorType, version). Example:
  {"descriptorType": {"$eq": "MCP"}}
