FAQ

What are the differences in Tool Router MCP and Oksign MCP?

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

Can I use Tool Router MCP with Claude Cowork?

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 Oksign tools.

Can I manage the permissions and scopes for Oksign while using Tool Router?

Yes, absolutely. You can configure which Oksign 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.

How safe is my data with Composio Tool Router?

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 Oksign data and credentials are handled as safely as possible.
