Use MCP servers in JetBrains Junie with Toolport
Toolport is a free, open source local MCP gateway. Add your servers to Toolport once, flip the JetBrains Junie toggle, and JetBrains Junie 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 JetBrains Junie on. Toolport writes its gateway entry into JetBrains Junie's config, next to anything already there.
- Restart or reload JetBrains Junie. Your full server set is available through Toolport, and any server you add later shows up without touching JetBrains Junie again.
Where JetBrains Junie keeps its MCP config
JetBrains Junie MCP config
All platforms ~/.junie/mcp/mcp.json
JSON with a top-level mcpServers object.
Good to know
- Toolport writes the user-scoped config only. Project-scoped Junie MCP configs are left untouched.
Why a gateway instead of JetBrains Junie's own server list?
- One setup, every agent. The same servers work in JetBrains Junie 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 JetBrains Junie'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.
