"H&M" matching MCP servers:

Hermetic memory for AI agents — one Rust binary, one SQLite file, zero network. Recall returns evidence with provenance or abstains: no code path for making things up.

Query clinical datasets like MIMIC-IV and eICU with natural language, supporting both tabular EHR data and clinical notes through a unified interface.

An MCP server that connects LLM assistants to LTspice/ngspice circuit simulation, enabling design, verification, and iteration on schematics and netlists with structured numeric results.
