FAQ

Frequently asked questions

With a standalone Supabase MCP server, the agents and LLMs can only access a fixed set of Supabase tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Supabase and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Supabase tools.

Yes, absolutely. You can configure which Supabase scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Supabase data and credentials are handled as safely as possible.
