MCP

Module: forge.lthn.ai/core/mcp Composer: lthn/mcp Binary: core-mcp

Model Context Protocol server exposing tools for file operations, process management, ML inference, RAG vector queries, webview automation, WebSocket streaming, and metrics. The Go side implements the MCP server with a subsystem plugin architecture and MCP-to-REST bridge. The PHP side provides a Laravel MCP module with tool registration, context services, and admin UI.

Architecture

The Go Service wraps modelcontextprotocol/go-sdk/mcp.Server and adds:

Sandboxed filesystem via go-io.Medium
Subsystem plugin system (Subsystem interface) for extending tool sets
Tool registry with JSON Schema extraction and REST bridge generation
Transport: stdio (default) or TCP (when MCP_ADDR is set)
