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.

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 gives AI agents access to verified, structured and typed knowledge — both as natural-language answers and structured data — as well as entity information.

Add to `~/.cursor/mcp.json`:

```json theme={null}
{
    "mcpServers": {
        "Cala": {
            "url": "https://api.cala.ai/mcp/",
            "headers": {
                "X-API-KEY": "YOUR_CALA_API_KEY"
            }
        }
    }
}
```

For more information, follow their documentation [here](https://cursor.com/docs/context/mcp#installing-mcp-servers).

Go to Settings → Developer → Edit Config and add the following JSON to the existing config file:

```json theme={null}
{
    "mcpServers": {
        "Cala": {
            "command": "npx",
            "args": [
                "mcp-remote",
                "https://api.cala.ai/mcp/",
                "--header",
                "X-API-KEY: YOUR_CALA_API_KEY"
            ]
        }
    }
}
```

For more information, follow their documentation [here](https://support.claude.com/en/articles/11175166-getting-started-with-custom-connectors-using-remote-mcp).

An example of the final config file could be:

```json theme={null}
{
  "preferences": {
    "coworkWebSearchEnabled": true
  },
  "mcpServers": {
    "cala": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://api.cala.ai/mcp/",
        "--header",
        "X-API-KEY: YOUR_CALA_API_KEY"
      ]
    }
  }
}

```

Add to `.vscode/mcp.json`:

```json theme={null}
{
    "servers": {
        "Cala": {
            "type": "http",
            "url": "https://api.cala.ai/mcp/",
            "headers": {
                "X-API-KEY": "YOUR_CALA_API_KEY"
            }
        }
    }
}
```

To support the full power of our graph's flexible schema, this MCP server utilizes dynamic JSON objects. This provides a "schema-less" experience for the LLM. Because of this, it is incompatible with OpenAI's "strict mode" so please ensure `strict: false` is set in your OpenAI specification.

For clients with built-in remote MCP support:

            "headers": {
                "X-API-KEY": "YOUR_CALA_API_KEY"

                "--header",
                "X-API-KEY: YOUR_CALA_API_KEY"
            ]
