   cd monarch-mcp-server
   

2. Install dependencies:

   Using pip:

   pip install -r requirements.txt
   pip install -e .
   

   Using uv (alternative):

   uv sync
   

3. Configure Claude Desktop: Add this to your Claude Desktop configuration file:

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

   Windows: %APPDATA%\Claude\claude_desktop_config.json

   {
     "mcpServers": {
       "Monarch Money": {
         "command": "/opt/homebrew/bin/uv",
         "args": [
           "run",
           "--with",
           "mcp[cli]",
           "--with-editable",
           "/path/to/your/monarch-mcp-server",
           "mcp",
           "run",
           "/path/to/your/monarch-mcp-server/src/monarch_mcp_server/server.py"
         ]
       }
     }
   }
   

   Important: Replace /path/to/your/monarch-mcp-server with your actual path!

4. Restart Claude Desktop

OR

3. Configure Claude Code (CLI): Add this to your Claude Code configuration file:

   Global (all projects):

   macOS/Linux: ~/.claude.json

   Windows: %USERPROFILE%\.claude.json

   {
     "mcpServers": {
       "Monarch Money": {
         "command": "/opt/homebrew/bin/uv",
         "args": [
           "run",
           "--with",
           "mcp[cli]",
           "--with-editable",
           "/path/to/your/monarch-mcp-server",
           "mcp",
           "run",
           "/path/to/your/monarch-mcp-server/src/monarch_mcp_server/server.py"
         ]
       }
     }
   }
   

   Project-level (specific directory):

   Create .mcp.json in your project directory:

   {
     "Monarch Money": {
       "command": "/opt/homebrew/bin/uv",
       "args": [
         "run",
         "--with",
         "mcp[cli]",
         "--with-editable",
         "/path/to/your/monarch-mcp-server",
         "mcp",
         "run",
         "/path/to/your/monarch-mcp-server/src/monarch_mcp_server/server.py"
       ]
     }
   }
   

   If installed via pip instead of uv, use:

   {
     "command": "python",
     "args": ["/path/to/your/monarch-mcp-server/src/monarch_mcp_server/server.py"]
   }
   

   Important: Replace /path/to/your/monarch-mcp-server with your actual path!

4. Restart Claude Code

2. One-Time Authentication Setup

Important: For security and MFA support, authentication is done outside of Claude.

Open a terminal and run:

cd /path/to/your/monarch-mcp-server
uv run python login_setup.py        # or: python login_setup.py

The script offers three login paths:

Option 1 (recommended): Session cookies from your browser

Long-lived sessions, supports SSO accounts, and sidesteps Cloudflare CAPTCHA gates on programmatic login. Steps:

1. Log in to https://app.monarch.com in Chrome or Firefox.
2. Open DevTools (F12) → Network tab.
3. Click any request whose Name starts with graphql (or any request to api.monarch.com).
4. Scroll to Request Headers, find the cookie: header, and copy the full value.
5. Paste it into the prompt.

The script verifies the cookies against the live API before saving them to your system keyring.

Option 2: Email and password

Standard interactive login. The script handles:

• Email verification codes (Monarch may send one for a new device session even when MFA is off).
• TOTP MFA codes if you have MFA enabled.
• Cloudflare CAPTCHA detection: if Monarch blocks programmatic login, the script tells you to switch to option 1.

The resulting long-lived session token is saved to your system keyring.

Option 3: Legacy session token paste

Kept for users with an existing token captured before the May 2026 API change. Monarch may no longer accept token-only auth on the GraphQL endpoint; if the verification call returns 401, fall back to option 1.
