"GNU" matching MCP servers:

Unit converter for AI agents, powered by the GNU units database — convert 3000+ units of measurement, evaluate compound unit expressions, reduce to SI base units, dimensional analysis. Offline, deterministic.

MCP server for GNU Radio

Provides fast, indexed code navigation (definitions, references, callers, etc.) for AI coding agents by leveraging GNU Global (gtags), dramatically reducing context noise compared to grep.

Enables natural language control of a live GNU Radio SDR flowgraph, allowing users to tune frequencies, adjust gain, capture IQ samples, analyze spectra, and detect signals through an MCP-compatible client.

Talk to your GnuCash books: a one-call financial dashboard (net worth, runway, budgets, what's overdue), and whole bank statements entered and reconciled in a single call from CSV, OFX, PDF, or even a screenshot or photo of the statement. Plus transactions, invoices, reports and multi-currency; local, SQLite/PostgreSQL/MySQL.

Enables recording a Wine or macOS program on an Apple silicon Mac and analyzing its GPU usage — GPU milliseconds per frame, frame pacing, FPS and memory — through Instruments' Metal System Trace, and also reads Metal .gputrace captures without Xcode and reports Apple's published GPU family facts. Recording, listing, comparing, and paging through traces and captures are exposed as tools that a shell or an AI coding agent can call directly.

Let me evaluate the README content.

Enables AI agents to run GPU acceptance tests on NVIDIA nodes you administer over SSH, executing DCGM diagnostics, a CUTLASS GEMM benchmark, HBM and PCIe bandwidth tests and NCCL all-reduce, then reporting each measurement against the matching profile's thresholds. Supports creating tests, tracking progress, sharing reports, and requires two owner-only confirmations before nodes are added or a test starts.

An MCP server that enables AI agents to query real-time NVIDIA GPU metrics like utilization, memory, temperature, and power without external monitoring tools.
