# mcp

[Model Context Protocol](https://modelcontextprotocol.io/) is a standard for exposing tools and data sources to AI systems. MCP servers can provide custom tools for databases, services, internal systems, local resources, and third-party APIs.

In Agent Forge, the MCP Tool block allows workflows to execute tools from MCP servers configured in workspace settings. This makes MCP a bridge between Agent Forge workflows and external tool ecosystems without requiring every tool to be built as a native Agent Forge integration.

### Usage Instructions

Configure an MCP server in workspace settings, then add the MCP Tool block to a workflow. Select the server, choose a tool exposed by that server, and fill in the dynamically generated arguments for that tool.

For a broader MCP setup guide, see the main [MCP documentation](file:///mcp).
