For developers

Architecture

Claude Desktop → MCP Server (stdio) → fetch() + _interslice_session cookie → ProjectX API

Setup from scratch

npm install
npm run build

The session is stored at ~/Library/Application Support/projectx-mcp/auth.json (gitignored).

On startup, if no valid session is found, Chrome opens automatically for login.

Build the installer

npm run build:installer   # generates projectx-mcp.pkg

The .pkg installs the app to /usr/local/lib/projectx-mcp/ and automatically writes the Claude Desktop config.

Test the API directly

npm run test:entry

Claude Desktop config (manual)

~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "projectx": {
      "command": "/usr/local/bin/projectx-mcp"
    }
  }
}

Troubleshooting

• Session expired → restart Claude Desktop, the browser opens automatically
• Chrome not found → install Google Chrome
• Project not found → ask Claude to run get_projects to see exact names
• post-install didn't write the config → manually edit the JSON above
