Getting a Zapier MCP URL and API key

First, you'll need to get a Zapier MCP URL and API key. This requires:

  1. Creating a Zapier account at zapier.com if you don't have one
  2. Going to mcp.zapier.com and selecting + New MCP Server
  3. Choosing OpenAI API as the client type: This provides API Key authentication, which works well with custom MCP clients like Mastra
  4. Adding tools to your server (e.g., search for "Gmail" and add "Find Email" and "Send Email")
  5. Selecting the Connect tab to find your MCP Server URL and API Key (select Rotate token to generate one if needed)

Important: Copy your API key immediately when it is shown. Zapier only displays it once. If you lose it, generate a new one by selecting Rotate token.

Add both values to your .env file:

bash
# Add these to your .env file
ZAPIER_MCP_URL=https://mcp.zapier.com/api/v1/connect
ZAPIER_MCP_API_KEY=your-api-key-here

Using environment variables keeps your credentials out of your source code. Ensure .env is listed in your .gitignore file.
