Redmine MCP Server for Zed

Zed extension that registers a redmine MCP context server and launches the standalone redmine-mcp-server executable.

This repository only maintains the Zed extension. The server implementation, GitHub Releases, and Homebrew formula are maintained in weirdo-adam/redmine-mcp-server.

Requirements

• Zed with MCP extension support
• Redmine REST API enabled
• Redmine API key with the required project permissions

Server Binary

The extension downloads the matching redmine-mcp-server GitHub Release binary automatically and caches it in the Zed extension runtime directory.

Zed Configuration

{
  "context_servers": {
    "redmine": {
      "settings": {
        "REDMINE_BASE_URL": "https://redmine.example.com",
        "REDMINE_API_KEY": "your-api-key",
        "REDMINE_MCP_READ_ONLY": true
      }
    }
  }
}

Configuration precedence:

1. Zed settings
2. Zed command.env
3. Environment inherited by the Zed process

Empty string values in Zed settings are ignored.

To use a manually installed server, set command explicitly:

{
  "context_servers": {
    "redmine": {
      "command": "/opt/homebrew/bin/redmine-mcp-server"
    }
  }
}

Settings

Server settings are documented in the standalone server repository.

Development

scripts/check.sh

The check script runs Rust formatting, type checking, Clippy, and the Zed WASI target check.

Publishing

This repository does not publish a plugin tarball or server archive. Zed extension publishing is handled through Zed's extension registry. Server Releases and Homebrew updates are maintained in the standalone server repository.

Security

Permissions are determined by the configured Redmine API key. Use the least privileged key practical for the target project, and keep real API keys in user-scoped Zed settings.

See SECURITY.md for vulnerability reporting.
