MCP for AI tools
Connect the MCP server with a read-only API key and query traffic, funnels and cohorts from your editor.
- 11 read-only tools
- Streamable HTTP
- Scoped by API key
{
"mcpServers": {
"pathclue": {
"type": "http",
"url": "https://…/mcp",
"headers": {
"Authorization": "Bearer <API key>"
}
}
}
}Use an API key with read access. The AI tool only sees the projects that key can read.
