Use MCP servers in Cursor with Toolport
Toolport is a free, open source local MCP gateway. Add your servers to Toolport once, flip the Cursor toggle, and Cursor gets all of them through a single gateway entry. Toolport picks a full tool list or search for each client, and you can change it in Clients.
Setup
- Download Toolport for Windows, macOS or Linux, and add your MCP servers to it (or import the ones your other AI agents already have; secrets go to your OS keychain).
- Open the Clients tab and toggle Cursor on. Toolport writes its gateway entry into Cursor's config, next to anything already there.
- Restart or reload Cursor. Your full server set is available through Toolport, and any server you add later shows up without touching Cursor again.
Where Cursor keeps its MCP config
Cursor MCP config
All platforms ~/.cursor/mcp.json
JSON with a top-level mcpServers object.
Good to know
- Servers installed by Cursor plugins live in plugin manifests, not mcp.json. Toolport reads those too, so its import and duplicate detection see your full setup.
Why a gateway instead of Cursor's own server list?
- One setup, every agent. The same servers work in Cursor and every other AI agent on your machine; add a server once and they all get it.
- Secrets in the OS keychain. API keys are injected at runtime and never sit in Cursor's config file.
- Watched by default. Rug-pull and tool-poisoning detection on every tool, plus per-tool governance and a destructive-tool kill switch. How the security works.
Free on this machine. Pro puts it on every machine. Team gives it to everyone.
