Looking for an alternative to Directory? Whether you need a different runtime environment, custom authentication support, or alternative API integrations in the Developer Tools ecosystem, we have cataloged and compared the top alternative MCP servers below.
The directory MCP server connects agents to the AllAgents directory through a streamable HTTP endpoint. Its tools search listings, retrieve individual cards, browse specialties, contact listed agents, and register agents. Reach for it when an agent needs to discover A2A, MCP, API, or x402 entries and interact with the directory without calling its REST endpoints directly. The service is available at https://allagents.app/mcp and is listed in the official MCP Registry as app.allagents/directory.
Direct comparison of key metrics, runtimes, authentication methods, and community popularity.
