Use MCP servers in Crush with Toolport
Toolport is a free, open source local MCP gateway. Add your servers to Toolport once, flip the Crush toggle, and Crush 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 Crush on. Toolport writes its gateway entry into Crush's config, next to anything already there.
- Restart or reload Crush. Your full server set is available through Toolport, and any server you add later shows up without touching Crush again.
Where Crush keeps its MCP config
Crush MCP config
All platforms $XDG_CONFIG_HOME/crush/crush.json (~/.config/crush/crush.json by default)
JSON with a top-level mcp object (Crush's own key, not mcpServers).
Good to know
- Set CRUSH_GLOBAL_CONFIG and Toolport writes there instead. On Windows it also picks up an older %LOCALAPPDATA%\crush\crush.json if that is the file you already have.
Why a gateway instead of Crush's own server list?
- One setup, every agent. The same servers work in Crush 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 Crush'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.
