Search 17,900+ open-source AI agents by capability, ranked by GitHub traction. Free, no key. That is what the beacon mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
Beacon indexes thousands of open-source AI agents from GitHub, ranked by real traction (stars, activity), searchable by capability. This MCP server puts that index inside Claude Desktop, Cursor, Cline, Windsurf, or any MCP client — so you can ask "find me an agent that does X" and get real, linkable results.
The server publishes 3 tools. What each one is for:
find_agent — Search agents by capability/task ("pdf extraction", "crypto trading", …)top_agents — Most-starred / highest-reputation agents in the indexagent_details — Full detail for one agent by id (e.g. elizaOS/eliza)Configuration is passed through the environment: BEACON_REGISTRY_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
beacon-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
This sits in the planning and project tracking group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Beacon's toolset — find_agent, top_agents, agent_details — is a fair guide to whether it matches your workflow. It is maintained by enrichgateagent-png; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Your workspace, on speaking terms with AI — search, read and write Notion pages and databases.
Issue tracking at the speed of conversation — Linear's official hosted server with OAuth and zero install.
Search and read your Drive — Docs, Sheets and files become context your assistant can actually use.
Your assistant inside the workspace — read channels, search history, post messages and tame the noise.
Metabase ships its own MCP endpoint — search your BI content, build and run queries, and save questions and dashboards without leaving the chat.
Stop letting your assistant hallucinate n8n node parameters — this server hands it the real schemas, templates and validation.
