"NEC" matching MCP servers:

Design and simulate wire antennas using the NEC2 method-of-moments solver via MCP. Supports dipole, Yagi-Uda, vertical, loop, and inverted-V geometries with pattern, impedance, and VSWR analysis.

Audits any site's UX the way a design-literate reviewer would — contrast, tap targets, type scale, colour discipline, scan patterns, copy — and returns the rule, the source line and the exact fix.

It enables AI assistants (Claude, Cursor, etc.) to access SEC EDGAR data through 6 structured tools — from discovering available filings to keyword-searching within their pages.

Enables passive security scanning of HAR files from QA test automation to detect missing security headers, insecure cookies, CORS misconfigurations, and leaked secrets, without making any live requests.

MCP server that enables natural-language-driven, headless HEC-RAS modeling, letting agents inspect, edit, run, compare, and plot 1D/2D hydraulic models without the GUI.

Enables cat food product search and ingredient analysis using natural language queries.

Enables web search and anonymous public-page retrieval through MCP, with provider-neutral selection, bounded plain-text results, and built-in auditing.

Transcribes audio files by referencing them in chat, using OpenAI's speech-to-text models locally without uploading audio, and supports speaker diarization.

Enables management of software requirements in compliance with IEC 62304 Class C medical device standards, including requirement creation, versioning, traceability matrix generation, and risk control integration.

A local RAG MCP server that indexes project documentation and code into ChromaDB for semantic search, supporting multiple tech stacks and deployment modes.

Adds a second-opinion advisor to OpenAI Codex CLI, enabling consultation with ChatGPT subscription, OpenAI API, Claude, Gemini, or OpenAI-compatible models during coding sessions.

Convert PDF, Word, Excel, PowerPoint, EPUB, HEIC and images from Claude, Cursor or any MCP client. 35+ conversion tools from convertica.net.

Convert PDF, DOCX, XLSX, images, and 20+ formats to Markdown using markdown.new API.

MCP server for SEC EDGAR filing intelligence, providing tools for fetching, chunking/embedding, retrieval, and evaluation of filings.

Enables agentic coding clients to enforce portable policy guardrails by evaluating proposed shell, file write, git, and network actions and returning allow, deny, or ask decisions.

Enables LLM-based assistants to diagnose network problems from PCAP/PCAPNG packet captures, offering tools for capture summaries, TCP conversation analysis, security anomaly detection, and JSON-RPC extraction without requiring Wireshark.

Enables AI assistants to query NYC capital project data (schedule, budget, lifecycle) using 16 tools with domain rules like PID↔FMS many-to-many and role-aware agency attribution.

A Model Context Protocol (MCP) server for Kerberos abuse operations using Rubeus on Windows or Impacket on Linux/macOS.

Enables AI agents to manage tasks on a local-first board via MCP, exposing task creation, updates, and queries through a thin adapter over the REST service.

Provides tools to search for people using registered business cards and the public Eight network. Enables LLMs to query person information while keeping private data secure.
