+- A Cursor plugin for the Cursor Marketplace: [plugins/agent-switchboard](https://github.com/assafbar2/agentswitchboard.dev/tree/main/plugins/agent-switchboard) adds the Agent Switchboard MCP server to Cursor in one install, with no account or key. Until the marketplace lists it, add the server by URL as [/connect](https://agentswitchboard.dev/connect) shows. ([#322](https://github.com/assafbar2/agentswitchboard.dev/pull/322))

+# Agent Switchboard for Cursor
+
+Search [Agent Switchboard](https://agentswitchboard.dev), a curated directory of AI agents, MCP
+servers and agentic tools, from Cursor's agent. Ask which tool fits a job, read a listing's setup
+steps, compare listings, find alternatives, and get one MCP config for several tools.
+
+The plugin adds one MCP server, `https://agentswitchboard.dev/api/mcp` (Streamable HTTP). It needs
+no account, API key or configuration. In approval prompts it appears as
+`plugin-agent-switchboard-agent-switchboard`.
+
+## Tools
+
+| Tool | What it does |
+| --- | --- |
+| `search_agents` | Find listings for a job: by query, task, category, access method (MCP, API, CLI, SDK and more), sign-in type, or official and verified status |
+| `get_agent` | One listing with its description, access methods, and MCP address or install command |
+| `list_categories` | The directory's categories, with how many listings each has |
+| `compare_agents` | Two or three listings side by side |
+| `alternatives_to` | Listings that could stand in for one, with what each has in common |
+| `connect_bundle` | One MCP client config for up to 10 listings, and how to connect the rest |
+| `submit_listing` | Suggests a missing product by filing a public GitHub issue for human review. It publishes nothing. It is marked destructive, so clients ask before calling it |
+
+Every tool except `submit_listing` is read-only.
+
+## Try it
+
+- "Find an MCP server that can query a Postgres database."
+- "How do I connect the Playwright MCP server, and is it official?"
+- "Compare GitHub Copilot, Cursor and Windsurf."
+- "What are good alternatives to Pinecone?"
+- "Give me one MCP config with Playwright MCP, GitHub MCP and Notion MCP."
+
+## Results and privacy
+
+Results are organic: they rank by relevance or A→Z, never by paid placement. The server receives
+only the arguments of each tool call, never your conversation or code. See the
+[privacy policy](https://agentswitchboard.dev/privacy).
+
+## License
+
+The plugin is MIT, like the rest of the repository's code. The catalog data its tools return is
+CC BY-NC 4.0; see [LICENSE-DATA](https://github.com/assafbar2/agentswitchboard.dev/blob/main/LICENSE-DATA).
