MCP Integration

The 4C:me Safe AI Platform integrates with the Model Context Protocol (MCP), enabling AI models to access external tools and data sources.

Accessing MCP Settings​

You can access MCP configuration from the chat settings sidebar. Click the settings gear (⚙️) icon in the top-right of 4C:me, then scroll down to find the MCP configuration button.

What Is MCP?​

The Model Context Protocol is a standard for connecting AI models to external tools, data sources, and services. MCP allows the AI to:

  • Call external tools during a conversation
  • Access data from connected services
  • Perform actions beyond pure text generation

MCP in the Platform​

Tool Call Indicator​

When the AI invokes an MCP tool during a conversation, a tool call indicator appears in the chat. This shows:

  • Which tool is being called
  • The status of the tool call
  • Results returned by the tool

Multiple MCP Servers​

The platform supports integration with multiple MCP servers, allowing connection to various external services and data sources simultaneously.

Improved Streaming​

MCP-enabled conversations feature improved response streaming:

  • Responses stream in real-time as they are generated
  • Fixed issues where responses would not stream when MCP was enabled (resolved in earlier updates)

MCP Handling​

The platform has greatly improved MCP handling with recent updates:

  • More reliable tool call execution
  • Better error handling when MCP tools fail
  • Improved integration between MCP tools and the chat interface

Authentication​

MCP servers are integrated with the platform's authentication system:

  • Secure connections to MCP servers
  • Token-based authentication for MCP tool calls
  • Proper staging and production monitoring via Sentry

Tips​

  • MCP tool calls may add slight latency to responses as external tools are invoked
  • Watch for the tool call indicator to understand when the AI is using external data
  • MCP is particularly useful for tasks that require real-time or external data
