MCP (Model Context Protocol)

ChatPharo can integrate with external tool servers via MCP. When enabled, MCP tools are exposed as callable tools to the model (similar to built-in and custom tools).

What MCP enables

• Connect to one or more MCP servers
• Discover server-provided tools
• Expose those tools to the active agent as “clients”
• Execute tools and return results into chat history

Configuration

Typical steps:

1. Enable MCP in settings.
2. Configure servers (command/host/port depending on implementation).
3. Connect servers.
4. Verify tools appear in the enabled tool list (or are usable by the agent).
