MCP Integration — Completion Summary

Completed: 2026-02-05 Plan: docs/plans/2026-02-05-mcp-integration.md

What Was Built

RAG Tools (pkg/mcp/tools_rag.go)

Three MCP tools added to the existing pkg/mcp server:

  • rag_query — semantic search against Qdrant vector DB
  • rag_ingest — ingest a file or directory into a named collection
  • rag_collections — list available Qdrant collections (with optional stats)

Metrics Tools (pkg/mcp/tools_metrics.go)

Two MCP tools for agent activity tracking:

  • metrics_record — write a typed event (agent_id, repo, arbitrary data) to JSONL storage
  • metrics_query — query events with aggregation by type, repo, and agent; supports human-friendly duration strings (7d, 24h)

Also added parseDuration() helper for "Nd"/"Nh"/"Nm" duration strings.

core mcp serve Command (internal/cmd/mcpcmd/cmd_mcp.go)

New CLI sub-command registered via cli.WithCommands() (not init()).

  • Runs pkg/mcp server over stdio by default
  • TCP mode via MCP_ADDR=:9000 environment variable
  • --workspace flag to restrict file operations to a directory

Registered in the full CLI variant. i18n strings added for all user-facing text.

Plugin Configuration

.mcp.json created for the agentic-flows Claude Code plugin, pointing to core mcp serve. Exposes all 15 tools to Claude Code agents via the core-cli MCP server name.

Key Outcomes

  • core mcp serve is the single entry point for all MCP tooling (file ops, RAG, metrics, language detection, process management, WebSocket, webview/CDP)
  • MCP command moved to go-ai/cmd/mcpcmd/ in final form; the plan's internal/cmd/mcpcmd/ path reflects the pre-extraction location
  • Registration pattern updated from init() + RegisterCommands() to cli.WithCommands() lifecycle hooks
  • Services required at runtime: Qdrant (localhost:6333), Ollama with nomic-embed-text (localhost:11434)
