Jmespath

Fourteen small MCP servers for everyday LLM / RAG / agent work. Each ships independently on npm, listed in the official MCP Registry, and is callable from Claude Desktop, Cursor, Cline, Windsurf, Zed, and any other MCP-compatible client.

RAG / agent helpers

Reliable transforms LLMs reach for tools instead of imagining

Sibling libraries

The first four wrap or re-implement logic from the user's Rust + Python work:

• ragdrift (crates.io) / ragdrift-py (PyPI) — five-dimensional drift detection
• embedrank, promptbudget, stopstream, citecite, ragmetric — pure-Rust crates from the rust-llm-stack workspace

The MCP servers are independent: they implement the logic they need in plain JavaScript so installing them doesn't pull a Rust toolchain.

Install (any of them)

Add to your MCP client config. Example for Claude Desktop:
