Authentication

The Fullstory MCP server authenticates using an API key passed as a request header. You generate the key in Fullstory settings and add it to your MCP client configuration.

Generate an API key​

  1. In Fullstory, go to Settings → Integrations → API Keys (fullstory.com/ui/{orgId}/settings/apikeys).
  2. Click Create API Key.
  3. Give the key a name (e.g., MCP) and copy the value. Store it securely; you won't be able to retrieve it again.

Configure your client​

Pass the API key as a Bearer token in the Authorization header of your MCP client configuration:

Add the following to your mcp.json (or equivalent configuration file for your AI client), replacing YOUR_API_KEY with the key you generated:

The url field points to the Fullstory MCP server. The headers object passes your API key with every request.

See Client Setup for step-by-step instructions for specific clients.
