Connect your agent to Cala’s MCP

You can use Cala via our MCP. To get started, you need to get an API key to authenticate your MCP client. Go to our Console and create a new API key.

Get Cala's API key

Create a free Cala account and get your API key.
With your API key in hand, you can connect your AI agent such as Cursor, Claude Desktop and others to our MCP server. Cala MCP connects AI agents to our knowledge search, including verified, structured and typed knowledge, as well as entities information.
Add to ~/.cursor/mcp.json:
{
    "mcpServers": {
        "Cala": {
            "url": "https://api.cala.ai/mcp/",
            "headers": {
                "X-API-KEY": "YOUR_CALA_API_KEY"
            }
