MCPVault

What it does

MCPVault is the independent quality directory for MCP servers. Browse 5,000+ servers with quality grades (A to F), staleness signals, install commands, and client compatibility. Verification is real: we spawn the server and run an actual MCP handshake (initialize + tools/list). Verified servers earn a do-follow link and an embeddable README badge. Maintainers claim their listing with GitHub sign-in in under a minute. Claiming and verification are free during early access.

Discover, claim and verify MCP servers. The independent, quality-first directory for the Model Context Protocol ecosystem.

18,383 servers from the Model Context Protocol ecosystem. Verified here means we actually connected: a real MCP handshake, re-run weekly, not static analysis. Grades refresh nightly. Built for developers, not enterprises. The honest software directory. Every fact labelled, no pay-to-rank. The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. Fair-code workflow automation platform with native AI capabilities. Combine visual building with custom code, self-host or cloud, 400+ integrations. Build Agentic workflows, RAG pipelines, with rich AI model and tool support on one…from mcpvault.io

  MCP PlaygroundNov 2025 · mcpplayground.io · ▲160

  MCP Playground is a Postman-style tool for MCP — inspect servers, execute tools live, test your client, all from the browser. Four things in one place: 1. Free hosted MCP servers — four public test servers anyone can point their client at: Echo (connectivity), Auth (Bearer token flow), Error (error handling), Complex (multi-tool schemas).No sign-up, just use the URL. 2. Server inspector — paste any remote MCP server URL, see all its tools/resources/prompts, execute them live, inspect the full JSON-RPC log. HTTP, SSE, and WebSocket all supported. 3. Registry — 10,000+ servers…

  MCPSpec – Ship reliable MCP servers without writing test codeFeb 2026 · light-handle.github.io · ▲7

  Hi HN, I've been building MCPSpec, an open-source CLI for MCP server reliability. Record sessions, generate mock servers, catch Tool Poisoning, and fail your CI build when something's wrong — without writing test code. There are ways to validate MCP servers today — the MCP Inspector, ad-hoc SDK scripts, unit tests for server internals — but nothing that handles regression detection, security auditing, mock generation, and CI pass/fail checks in one tool. MCPSpec does that: 1. Record a session against your real server, replay it after changes to catch regressions 2. Generate a standalone…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
