A production, read-only MCP server for finding cryptographically verified AI agents and production agent-first packages in the AbsoluteJS public registry. It gives MCP clients one installable discovery surface for agent names, capabilities, protocols, publishers, authentication metadata, and signed descriptors.
Run it
No credentials are required. The server fetches the public HTTPS registry, refuses redirects, bounds response size and time, validates every record, and caches successful indexes briefly. To use a compatible federated registry, set ABSOLUTE_AGENT_REGISTRY_URL to its HTTPS index URL. The package catalog is independently configurable with ABSOLUTE_PACKAGE_REGISTRY_URL.
MCP surface
search_agents filters verified listings by text, capability, and MCP/A2A/
Arazzo/WebMCP/HTTP/OpenAPI/WebSocket interface type, with bounded pagination.
get_agent returns one listing by canonical discovery ID or agent URL.

search_packages filters the production AbsoluteJS catalog by purpose,
category, and supported standard.
get_package returns one package by exact scoped npm name.
registry_status reports freshness, schema, endpoint, and verified count.
absolute-agents://registry/index exposes the validated index as a resource.
absolute-agents://packages/index exposes the validated package catalog.
All tools are marked read-only. Discovery never grants authorization: callers must follow each returned agent's advertised OAuth, approval, and delegation requirements before taking actions.
Library use
The npm package declares mcpName: io.github.absolutejs/agents and ships the official MCP Registry server.json metadata alongside its AbsoluteJS manifest.

Trace from the first failed boundary
Reproduce the smallest canonical @absolutejs/agents-mcp example, confirm the supported entry point and version in the API explorer, then inspect the first boundary that did not produce its documented result.
