I posted MemoTrail here a few weeks ago — a local MCP server that gives your AI coding assistant long-term memory across sessions. The feedback was great, and I shipped a major update based on it.

  For those new here: every Claude Code or Cursor session starts from zero.
  MemoTrail auto-indexes all your past sessions and makes them searchable.
  Two commands to set up:

    pip install memotrail
    claude mcp add memotrail -- memotrail serve

  Then ask: "Why did we switch to Redis?" — and it finds the exact session.

  What's new in v0.3.0:

  • Cursor IDE support — MemoTrail now indexes Cursor chat history too
    (parses state.vscdb files). Not just Claude Code anymore.

  • BM25 keyword search — v0.2 only had semantic search. Now there's also
    exact keyword matching (great for error messages, function names) and a
    hybrid mode that combines both using reciprocal rank fusion.

  • Auto session summaries — every session gets a human-readable summary
    automatically. No API keys, no LLM calls — pure heuristic extraction.

  • Auto decision extraction — detects architectural decisions from conversations
    ("decided to use X", "let's switch to Y") and categorizes them. Months later
    you can ask "what tech decisions did we make?" and get real answers.

  • Real-time file watching — new sessions are indexed instantly via watchdog.
    No more restarting the server to pick up new conversations.

  • 3 chunking strategies — token-based (default), turn-based (groups
    user+assistant pairs), and recursive (splits on paragraph/sentence boundaries).
    Different strategies work better for different use cases.

  • VS Code extension — search, index, and view stats directly from VS Code
    sidebar without touching the terminal.

  • 69 tests — up from 12. Covers all new modules.

  Still 100% local. No cloud, no API keys, no data leaves your machine.

  What hasn't changed: ChromaDB + SQLite storage, all-MiniLM-L6-v2 embeddings
  on CPU, MCP protocol, ~/.memotrail/ for all data.

  Next up: GitHub Copilot collector, cloud sync (opt-in), and team memory sharing.
