Policylayer MCP Registry

Local-first code retrieval for AI agents — cuts codebase context from tens of thousands of tokens to a few hundred, with zero hallucinated file paths.

Browser automation and web scraping

Is this song AI or human? SongCheck detects AI-generated music (Suno, Udio, and more) and media from any AI agent. Point it at an audio file, an image/video, or a whole music folder and it returns a verdict (LIKELY AI-GENERATED / UNCERTAIN / LIKELY HUMAN), an AI-probability score, confidence, and provenance signals (Content Credentials / SynthID watermark, generator hints). Tools: detect_ai_music, detect_ai_media, scan_catalog (audit an entire catalog), and songcheck_health. Free tier is 5 checks/day; a paid key unlocks unlimited catalog scans. Powered by SongCheck (Khaled Media), a self-hosted v9 ensemble detector.

A Model Context Protocol (MCP) server that integrates with Jina AI Search Foundation APIs.

Create a remote sandbox that can execute code/run commands/upload and download files. 创建远程沙盒，可以执行代码/运行命令/上传下载文件

A Model Context Protocol Server connector for Perplexity API, to enable web search without leaving the MCP ecosystem.

Official Firecrawl MCP Server - Adds powerful web scraping to Cursor, Claude and any other LLM clients.

Flag features directly from chat in your code editor, including VS Code, Cursor, Windsurf, Claude Code—any IDE with MCP support.

An MCP server implementation that provides a tool for dynamic and reflective problem-solving through a structured thinking process.

AI image generation using various models

Discover ranked, actively-maintained Claude and MCP tools by task. Query the Claudeers ecosystem registry directly from your agent — search_tools returns tools with health status, community ratings, and merit-only ranking, so you find what actually works instead of a raw keyword search. get_tool and list_categories round out discovery. Read-only, no auth, remote HTTP.

Language models generate; Concordance verifies. The verify tool checks a claim deterministically (no model in the loop) and returns HOLDS / BROKEN / INCOMPLETE with the worked reasoning and a sealed receipt (content_hash + cite_url) that re-fetches byte-identical or not at all. Also: ranked search over an ~11k-record library, seal_fetch to re-verify any receipt, redact to strip PII before text travels, and a sealed connection graph. Runs sovereign/offline too (stdlib-first Python). A public false-positive benchmark covers every domain: the engine has never sealed a falsehood. 38 tools live; remote endpoint at https://narrowhighway.com/mcp.

A Serper MCP Server

Browse and install 75+ free animated, shadcn-compatible React components from AI Canvas, each with AI reproduction prompts. Read-only MCP server over the live aicanvas.me registry; eight tools.

Read-only database access with schema inspection

Public, read-only MCP over the complete 64-hexagram I Ching corpus — hexagrams, trigrams, changing lines, and reading context from an original English translation. Deterministic lookup only; no casting or divination.

fw-context builds a compiler-accurate semantic index of your C/C++ firmware from compile_commands.json and the libclang AST. Instead of reconstructing the program from text, the LLM queries a persistent index for symbol definitions, callers, callees, callback registrations, function pointer assignments, inheritance, and active source code. 31 MCP tools. Powered by libclang + SQLite + FTS5 + vector search. For Zephyr, PlatformIO, Mbed OS, Arduino, FreeRTOS — any build that produces compile_commands.json.
