Claude Code

Connect the Fullstory MCP server to Claude Code to query your product data directly from the terminal.

Prerequisites​

Setup​

Add the MCP server using the claude mcp add command. Set a FULLSTORY_API_KEY environment variable first, then run (note the single quotes around the header value; this prevents your shell from expanding ${env:...} before Claude Code can):

export FULLSTORY_API_KEY=your_api_key_here
claude mcp add --transport http fullstory https://api.fullstory.com/mcp \
  --header 'Authorization: Bearer ${env:FULLSTORY_API_KEY}'

Or add it manually to your Claude Code configuration file (~/.claude/mcp.json):

{
  "mcpServers": {
    "Fullstory": {
      "url": "https://api.fullstory.com/mcp",
      "headers": {
        "Authorization": "Bearer ${env:FULLSTORY_API_KEY}"
      }
    }
  }
}

Verify the connection​

Start Claude Code and run:

/mcp

Fullstory should appear in the list of connected servers with its tools available.

Using the tools​

Once connected, you can ask Claude Code questions about your product data in natural language:

  • "What are the top frustrations on our product right now?"
  • "Build a segment of users who rage clicked on the payment page and summarize 3 sessions for me."
  • "What's causing the most drop-off in our checkout funnel, and can you show me what those sessions look like?"
