Claude Desktop

Claude Desktop uses a local stdio MCP server definition.

Config file location

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

Use an absolute host path for the workspace mount. Claude Desktop will not expand project-local placeholders such as ${workspaceFolder} in this config.

{
  "mcpServers": {
    "pwno-mcp": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "--cap-add=SYS_PTRACE",
        "--cap-add=SYS_ADMIN",
        "--security-opt",
        "seccomp=unconfined",
        "--security-opt",
        "apparmor=unconfined",
        "-v",
        "/ABSOLUTE/PATH/TO/YOUR/PROJECT/workspace:/workspace",
        "ghcr.io/pwno-io/pwno-mcp:latest",
        "--stdio"
      ]
    }
  }
}

Restart Claude Desktop after editing the config, then confirm pwno-mcp appears in the MCP server list.
