Automatic Setup

cohaku init
This detects Claude Desktop and writes to the config file automatically.

​
Manual Setup

Edit the Claude Desktop config file:
  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "cohaku": {
      "command": "cohaku",
      "args": ["mcp"]
    }
  }
}
Or if using npx: 
{
  "mcpServers": {
    "cohaku": {
      "command": "npx",
      "args": ["-y", "@cohaku/cli", "mcp"]
    }
  }
}
Claude Desktop requires full paths to executables. cohaku init handles this automatically by resolving the absolute paths to Node.js and the cohaku binary.

​
Verify

Restart Claude Desktop and check that Cohaku tools appear in the MCP tools list.
