Go Tools by Fabricators

Remote MCP server for the go-tools ecosystem.

Endpoint: https://go-tools.fabricators.ltd/mcp

Exposes four tools to any MCP client (Claude, Cursor, Windsurf, Copilot CLI, …):

Tool	Description
list_modules	All top-level modules with import paths and one-line descriptions
get_module(name)	Complete docs for a module — API, examples, integration notes
search_modules(query)	Full-text search across all module docs
get_ecosystem	Integration diagram + design principles

Indexed modules (post-v1.1.0 consolidation): go-foundation (40+ pkg/ subpackages: auth, caching, routing, DI, FSM, jobs, logger, metrics, …), go-slipstream, go-warp/v1, go-wormhole.

Setup

pnpm install   # installs deps AND generates data.ts from go-tools-index.md

Local development

pnpm dev       # wrangler dev → http://localhost:8787/mcp

Test with MCP Inspector:

pnpm dlx @modelcontextprotocol/inspector@latest
# Connect to: http://localhost:8787/mcp

Deploy

pnpm deploy    # wrangler deploy → https://go-tools.fabricators.ltd/mcp

  "mcpServers": {
    "go-tools": {
      "url": "https://go-tools.fabricators.ltd/mcp"
    }
  }
}

Update the index

pnpm update-index   # re-embeds go-tools-index.md into data.ts
pnpm deploy         # redeploy

Architecture

• Transport: Streamable HTTP (serve("/mcp")) — MCP 2025 standard, single POST /mcp endpoint
• No auth — public documentation, no OAuth required
• No external storage — index content is bundled into the Worker at deploy time
• Durable Objects — McpAgent uses a DO for MCP session state (required by the protocol)
