AI client integration
Connect Cursor through MCP Beast — one endpoint, every MCP server.
Point Cursor at one MCP Beast endpoint instead of maintaining a per-project mcp.json full of servers and pasted API keys.
The token problem
How MCP setup in Cursor normally sprawls.
Cursor reads MCP servers from JSON config, and every server you add wants its own credential — a GitHub PAT here, a Supabase token there — sitting in plaintext config or environment variables. Multiply that across projects and machines and you end up re-pasting the same secrets again and again, with no way to rotate them in one place.
Credential copies in client configs are also a security problem, not just a chore — see the token-passthrough discussion in our MCP security guide.
How it works
Point Cursor at one endpoint.
Install the free MCP Beast app on your Mac and add your MCP servers to it once — credentials go into the macOS Keychain, not into config files.
Add a single MCP Beast entry to Cursor's MCP configuration, pointing at the gateway's local endpoint.
Cursor now reaches every connected server through that one entry. Add or rotate a server credential in MCP Beast and Cursor picks it up without touching its config.
This is the core of the gateway model: clients connect through MCP Beast, servers are connected to it. Read the full picture in the MCP gateway guide.
FAQ
Cursor + MCP Beast questions, answered.
Does Cursor support MCP gateways?
Yes. To Cursor, MCP Beast looks like any other MCP server — you add one entry to Cursor's MCP config and the gateway routes requests to the right downstream server behind it.
Where do my API keys live when Cursor connects through MCP Beast?
In the macOS Keychain, managed by the MCP Beast app. Cursor's config only references the gateway endpoint, so no per-server tokens sit in Cursor's JSON files.
Will routing Cursor through a gateway bloat my context window?
The opposite. Instead of loading every tool schema from every server, MCP Beast exposes a compact dispatcher and resolves the right tool via semantic routing, so less schema noise enters each request.
