MCP server registry and marketplace - discover, install, activate tools on demand
Search spans the official MCP registry, npm, and PyPI in one query, so popular servers that aren't in the official index (Microsoft @playwright/mcp, @modelcontextprotocol/server-*, mcp-server-fetch, mcp-server-git, …) all show up.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
| Tool | What it does |
|---|---|
| find_tool | **Single-call discovery.** Hybrid BM25 + semantic search → top match + confidence label + compact required_args + 4 alternatives. Auto-activates the owning server. |
| find_tools | **Batch discovery.** Pass intents: [...] to discover N tools in one round-trip. Use for multi-step tasks. |
| get_schema | Full input_schema for a discovered tool. Only needed when the compact required_args summary isn't enough (conditional / polymorphic args). |
| proxy_call | Invoke a discovered tool **through** agent-discover without exposing it to the host catalog. Pair with find_tool({auto_activate: false}) for huge catalogs. |
| list | Search the local registry by server (FTS5). |
| uninstall | Remove a server. |
| activate | Start a server, discover its tools, expose them to the host as serverName__toolName. |
| deactivate | Stop a server, hide its tools. |
| browse | Federated search across the official MCP registry, npm, and PyPI. |
| status | Active servers summary (names, tool counts, tool lists). |
