projectx-mcp

Log hours in ProjectX by talking to Claude Desktop.

"Log 8 hours of Ontrac for today" "Fill in the missing days this week with Ontrac" "Which days am I missing hours for this month?"

Installation

macOS (automated)

git clone git@github.com:agustindiezdb/projectx-mcp.git
cd projectx-mcp
bash scripts/install.sh

The script will:

• Install dependencies

• Build the project

• Configure Claude Desktop automatically

• Create a backup of your existing config

Then restart Claude Desktop. Chrome will open automatically for login with your Dualboot Google account.

That's it! You can now ask Claude to log your hours.

Windows

git clone git@github.com:agustindiezdb/projectx-mcp.git
cd projectx-mcp
npm install
npm run build

Then manually edit Claude Desktop config:

Open: %APPDATA%\Claude\claude_desktop_config.json

Add:

{
  "mcpServers": {
    "projectx": {
      "command": "node",
      "args": ["C:\\full\\path\\to\\projectx-mcp\\dist\\src\\server.js"]
    }
  }
}

Replace C:\\full\\path\\to\\ with your actual path (use \\ for Windows paths).

Then restart Claude Desktop. Chrome will open automatically for login.

Manual installation

If you prefer to configure manually:

1. Clone and build:

   git clone git@github.com:agustindiezdb/projectx-mcp.git
   cd projectx-mcp
   npm install
   npm run build

2. Edit Claude Desktop config:
   Open ~/Library/Application Support/Claude/claude_desktop_config.json and add:

   {
     "mcpServers": {
       "projectx": {
         "command": "node",
         "args": ["/ABSOLUTE/PATH/TO/projectx-mcp/dist/src/server.js"]
       }
     }
   }

   Replace /ABSOLUTE/PATH/TO/ with the full path to your cloned repo.

3. Restart Claude Desktop

Using with Cursor

Cursor uses a per-project MCP config. Create .cursor/mcp.json in your project root:

{
  "$schema": "https://json.schemastore.org/mcp.json",
  "mcpServers": {
    "projectx": {
      "command": "node",
      "args": ["/ABSOLUTE/PATH/TO/projectx-mcp/dist/src/server.js"]
    }
  }
}

Replace /ABSOLUTE/PATH/TO/ with the full path to your cloned repo.

Then restart Cursor. The first time, Chrome will open for login.

Usage

Just talk to Claude naturally:

Log 8 hours of Ontrac for today with description "Sprint planning"

Check my entries for this week and fill the missing days with 8h of Ontrac

Delete yesterday's entry and log 4h of Internal — Administrative

Which days am I missing hours for April?

Available tools

If login fails or the session expires

Simply restart Claude Desktop. Chrome will open again for you to sign in.

Useful scripts

You can also use the API directly without Claude Desktop:

# Test the API (creates and deletes a test entry)
npm run test:entry

# Check which days you're missing hours in April
npx ts-node scripts/check-april.ts

# Manually refresh your session (if expired)
npm run save-session

For developers

Architecture

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

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

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

Development mode

npm run dev

This runs the server with ts-node for rapid development (no build step needed).

How it works

1. Authentication: Uses Playwright to open Chrome and auto-detect when login is successful by polling /api/v1/current_user

2. Session persistence: Saves cookies to auth.json using Playwright's storageState()

3. API client: Reads the _interslice_session cookie and makes authenticated requests to ProjectX

4. MCP protocol: Exposes 4 tools to Claude Desktop via stdio transport

Claude Desktop config (manual)

If you prefer to edit manually:

{
  "mcpServers": {
    "projectx": {
      "command": "node",
      "args": ["/path/to/projectx-mcp/dist/src/server.js"]
    }
  }
}

Troubleshooting

• Session expired → restart Claude Desktop, Chrome opens automatically

• Chrome not found → install Google Chrome (must be in system PATH)

• Project not found → ask Claude to run get_projects to see exact names

• Path issues (macOS/Linux) → use absolute paths, not ~ or relative paths

• Path issues (Windows) → use \\ (double backslash) in JSON paths, e.g. C:\\Users\\...

• Auth file location:

  • macOS: ~/Library/Application Support/projectx-mcp/auth.json

  • Windows: %APPDATA%\projectx-mcp\auth.json

  • Linux: ~/.config/projectx-mcp/auth.json

Requirements

• OS: macOS, Windows, or Linux

• Node.js: 20+

• Browser: Google Chrome (required for auto-login)

• Claude Desktop

• Dualboot Google account
