MCP Action Gateway

MCP security before the tool call executes.

Put an action-policy decision between your MCP host or gateway and the tools that change business systems.

Where the action needs a decision

MCP connects agents to tools, data and APIs. A reachable server and a schema-valid request still leave a business question: should this actor use this tool, with these arguments, for this purpose?

Route the tool request

Connect the host or gateway at its forwarding boundary so the final server, tool name and arguments are available before execution.

Evaluate the action

Apply tenant policy to identity, purpose, destination and delegated authority, then return the decision to the boundary.

Enforce and verify

Block denied requests before forwarding, apply sanitised arguments where supported, and retain the decision and available outcome evidence.

Build a testable deployment.

Integration Copilot can inspect the local MCP role, language, transport and candidate forwarding boundaries, prepare an unapplied integration patch, and help verify allowed, blocked, sanitised and fail-closed behaviour. Review the proposed change before applying it.

See the decision before the action.

Try a local scenario, then bring your workflow to a deployment review. Start with one agent and one tool, and see exactly where the action can be stopped.
