Model Context Protocol (MCP)
ZeroTrust Agents includes native support for the Model Context Protocol, enabling transparent interception of tool calls between applications and MCP servers.
Supported Transports
The Gateway supports both standard MCP transport options:
- Stdio Transport: For local development and command-line tool integrations.
- SSE (Server-Sent Events) Transport: For cloud-native microservices and distributed deployments.
How MCP Security Works
When an agent calls a tool via the MCP client, the Gateway intercepts the tools/call JSON request. It evaluates parameters against policy constraints, then either forwards the call to the actual MCP server or returns a mock/blocked error response to the client.
