qdrant-mcp-server (maintained fork)

Fork of the abandoned PyPI package qdrant-mcp-server 0.1.0 (author fiyen; upstream github.com/fiyen/qdrant-mcp-server is 404 — no repo exists to PR against).

Why this fork exists

The original eagerly loads a sentence-transformers/all-MiniLM-L6-v2 model in __init__. As a stdio MCP server, every agent runtime/session spawns its own copy, so N idle sessions pin N × ~1.35 GB of duplicated model memory (measured: 5 copies = 5.7 GB). See the generalized "stdio trap" write-up.

Changes vs PyPI 0.1.0

  • Lazy-load patch: the embedding model loads on the first generate_embedding call instead of at startup. Idle copies cost ~30 MB. (lazy-load.patch in the repo root is the diff for reference.)

Install (replaces the PyPI install)

uv tool install --force git+https://github.com/Ripnrip/qdrant-mcp-server

Then the existing MCP configs (command = /Users/admin/.local/bin/qdrant-mcp-server) keep working, and future uv tool upgrade pulls from this fork, not dead PyPI 0.1.0.

After any reinstall, restart running qdrant-mcp-server instances (the Swift reaper LaunchAgent handles orphan cleanup: com.local.qdrant-mcp-reaper).
