Connectors

Extend your workspaces with MCP integrations

Connectors are MCP (Model Context Protocol) integrations that extend what Calvin's agents can do within a workspace. While Blocks add infrastructure and skills to the workspace itself, Connectors bridge the gap between Calvin and your external tools, services, and data sources.

You can manage connectors at the workspace level through the Connectors button in the workspace toolbar, or from the workspace list page using the plug icon on each workspace card. You can also add a connector during a chat session through the "+" menu in the chat input.

When you click the Connectors button inside a workspace, a panel opens showing all connectors currently configured for that workspace. From here you can view existing connections, add new ones, or remove connectors you no longer need. Each connector extends the agent's capabilities by giving it access to additional tools and data that it can use when executing tasks.

Connectors follow the MCP standard, which means they provide a standardized interface for AI agents to interact with external systems. This makes it possible for Calvin's agents to read from and write to external services as part of their normal task execution — without you needing to write custom integration code.
