MCP Servers

Community pronunciation dictionary for developer project / product / jargon names (kubectl, nginx, GIF, JSON, Pydantic, Knative, LaTeX — 1,848 entries). Each entry carries IPA, a General-American respelling, alternate readings where the pronunciation is contested, a source citation (creator interview / project FAQ / Wikipedia § Pronunciation), and a confidence level. Tools: pronounce(word), searchpronunciations(query), listpronunciations(category). Install: uvx pronounce-mcp. Live browse: .

📟 - MCP server that lets AI agents drive real 3D printers end to end — design, slice, queue, monitor via camera, and recover from failures — across Bambu Lab, Creality, Prusa, Elegoo, and more over OctoPrint, Moonraker/Klipper, PrusaLink, and USB. AGPL-3.0, pip install kiln3d.

📟 - CNC machine control via Universal G-code Sender (GRBL). Jog axes, home, run G-code files, inspect toolpaths, estimate cycle times. Motion commands require two-step token confirmation — Claude cannot move hardware autonomously.

📟 - Build-aware code intelligence for embedded C/C++ firmware. Indexes your project from compilecommands.json via libclang into SQLite+FTS5. 31 MCP tools for symbol search, call graphs, hotspot analysis, dead code detection, and vector search. For Zephyr, PlatformIO, Mbed OS, Arduino, FreeRTOS.

📟 - Control an OBSBOT Tiny 2 webcam over USB — pan/tilt/zoom the motorized gimbal in degrees, AI subject tracking, presets, focus/exposure/white-balance, snapshots and recording. Point it at a pixel, or zoom to fit a region of a snapshot it just took. 35 tools (34 on Linux), speaking UVC and the vendor protocol directly with no vendor SDK and no cloud; prebuilt native helpers for Windows, macOS and Linux. npx obsbot-mcp

📟 - Page-cited retrieval of embedded/firmware reference docs (datasheets, MCU registers, Modbus/CAN, SCPI, IEEE 1547/SunSpec) for coding agents — returns verbatim source snippets with page citations, or "no confident match" instead of a fabricated value. No signup or API key.

Build any Telink/embedded SDK (Eclipse headless / Make / generic) via natural language. Auto-detects build pattern and exposes buildinfo/buildrun/buildlist MCP tools. Cross-platform.

Generate diagrams from structured JSON across 18 types (architecture, ERD, sequence, flowchart, Gantt…) — native SVG/PNG, no headless browser. Built for LLMs and agents.

Zero-dependency chart server that renders bar, line, pie, scatter, and more from JSON or CSV to SVG, HTML, PNG, or data URL. Built-in themes; PNG output renders inline in chat. Install via uvx --from charted[mcp] charted-mcp.

Word-sized charts (sparklines, bars, bullets — 106 types) rendered to self-contained SVG with generated alt text. Three tools: find the right chart for a question, get its wiring, render it. Works in chat surfaces that can't run React. Install via npx -y @microcharts/mcp.

Unit conversion and dimensional analysis backed by the bundled GNU units database (3000+ units, compound expressions, reduction to SI base units). Offline and deterministic. uvx mcp-gnu-units.

Profiles tabular data files (CSV, TSV, Parquet, Excel, JSON) for LLM agents: one-call dataset overview, per-column statistics, a data-quality audit (missing values, duplicates, mixed types, outliers), and memory-saving dtype suggestions. Pure Python (pandas); files are read locally and nothing leaves your machine. pip install data-profiler-mcp.

Compares approximate filter data structures (Bloom, Counting Bloom, Cuckoo, SuRF) via MCP

Airtight math for agents: 3.7M-theorem search, PSLQ constant ID, OEIS, real Lean kernel checks, applicability checklists. No LLM inside, no API key.

Probes your live API and classifies why each endpoint failed (root cause + evidence + calibrated confidence) over MCP, so your AI assistant debugs from evidence instead of guessing. Deterministic rules, no black box. Works with FastAPI, Express, Next.js, tRPC, and GraphQL. npm i -g qa-probe

Lets the non-technical people you build for request UI changes directly on your live site, then pulls each request (with the exact element and page) into your coding agent so it builds it on a branch and opens a pull request. Works with Claude Code, Cursor, Cline, Codex, and remote agents over HTTP. npx -y amendor-mcp

Build, sign, and publish iOS and Android apps through AI agents. Integrates Codemagic CI/CD, App Store Connect, and Google Play in one server.

Gives any AI assistant real architectural understanding of a codebase: tech-stack overview, internal dependency graph with cycle detection, risk hotspots, and module summaries. Local, zero-config, no API keys. uvx mcp-architect.

Order groceries from Yandex Lavka (Russia): search the catalog, build a cart, and place an order with a two-step confirmation before any charge. Unofficial (reverse-engineered private web API); local stdio or remote HTTP with OAuth. uvx yandex-lavka-mcp.

Compare parcel and letter delivery prices across 60+ carriers in 27 European countries. Remote MCP: packzoo.com/api/mcp.

Deterministic guardrail for AI-written diffs, runnable from inside the coding agent's own loop over MCP. Zero-LLM-token, AST-precise rules (SQLi, SSRF, XXE, permissive CORS, prototype pollution, hardcoded secrets) across 8 languages, plus structural checks for reinvented helpers and over-abstraction — findings scoped to only the changed lines, same input always gives the same output, no false-block guarantee. npm i -g diffgate-review (registers as the diffgate command; diffgate mcp starts the se

🎖️ - Deterministic axe-core accessibility scanning (WCAG 2.1 AA, EN 301 549, PDF/UA) through a wcagc account: scan any public URL or PDF, crawl a whole registered site, replay saved multi-step journeys, and read violation trends. Returns structured findings — rule, severity counts and the success criteria involved — so the assistant reasons over real results rather than guessing from markup. Every scan result carries an automated-coverage disclaimer instead of a score or a pass/fail verdict. Ho

Search @imqueue docs and scaffold typed services & clients for AI coding agents, access CLI and manage your service fleet.

MCP server for quelllm.fr — open-weights LLM catalog (250+ models with params, VRAM by quantization, tokens/sec, license). Tools: listmodels, getmodel, compare, estimatevram, estimatecost (API providers vs self-hosted hardware in EUR), searchmodels. Useful when picking a local model that fits your GPU/Mac.
