MCPVault is an independent, quality-focused directory of MCP (Model Context Protocol) servers, built for developers who are connecting AI agents like Claude, ChatGPT, Cursor, and Windsurf to real tools and data.
Why it exists
MCP is the "USB-C for AI agents": an open protocol (created by Anthropic, donated to the Linux Foundation, adopted by OpenAI, Google, and Microsoft) that lets any AI client talk to any tool server. The ecosystem exploded to tens of thousands of public servers, but discovery is broken. Existing directories are either enterprise platforms or raw data dumps. You cannot tell which servers are maintained, which ones actually start, or which clients they work with.
The directory
MCPVault auto-ingests MCP servers from GitHub (5,000+ live, refreshed nightly) and enriches each listing with:
- Quality grade (A to F) based on recency, adoption, license, and documentation signals.
- Staleness signals: last commit date, archived status.
- Install command, extracted from the README and copy-paste ready.
- Client compatibility: Claude Desktop, Claude Code, Cursor, Windsurf, VS Code, Zed, Cline, ChatGPT.
- Tool-level pages: every tool a server exposes gets its own indexed page (26,000+ and growing).
Live verification (the differentiator)
Most directories check that a link resolves. MCPVault actually runs the server: the verification harness spawns it in a sandbox (npx/uvx runners only) and requires a real MCP stdio handshake, initialize followed by tools/list. Servers that pass earn the "Verified & Working" badge and a do-follow website link. Verification is re-checked weekly; if a server stops responding, the badge lapses automatically. The badge state is live everywhere it is embedded.
Claiming (free)
Auto-ingested listings start as minimal "stale" listings with a clear call to action: is this your MCP server? Claim it. Maintainers sign in with GitHub, prove push access to the repo, and take control: edit the description, category, topics, compatibility flags, install command, and homepage, and upload a logo. One account can manage multiple servers.
Verification (free during early access)
Claimed servers can request verification. Two checks: the server must pass the live MCP handshake, and the MCPVault badge must be visible in the repo README or project site. Both are re-checked on every run. The badge is earned, never bought, and that stays true permanently.
Embeddable badges
Every server gets a status-aware SVG badge (Listed / Claimed / Verified) with light and dark variants, plus ready-made README and HTML snippets. Badges always reflect the current status.
Pricing
- Free: full directory, search, tool pages, claiming, listing editing, logo upload.
- Verified badge: free during early access (paid tier planned later; early verified servers keep the badge as long as they keep passing).
- Sponsored / featured placement: planned, not yet live.
Features
- 5,000+ MCP servers auto-ingested from GitHub, refreshed nightly
- Quality grades A to F based on recency, adoption, license, and documentation signals
- Live verification: verified servers are spawned in a sandbox and must pass a real MCP handshake (initialize + tools/list), re-checked weekly
- 26,000+ tool-level pages: every tool inside a server gets its own indexed page
- Client compatibility flags: Claude Desktop, Claude Code, Cursor, Windsurf, VS Code, Zed, Cline, ChatGPT
- Install commands extracted per server, copy-paste ready
- Staleness signals: last commit date, archived status
- Free claiming via GitHub sign-in with real push-access verification
- Owner listing editor: description, category, topics, compatibility, install command, homepage, logo upload
- Status-aware embeddable badges (Listed / Claimed / Verified) in light and dark variants
- Do-follow website link for verified servers
- Verification badge is earned, never bought
Use Cases
- Find MCP servers that actually work before wiring them into Claude, Cursor, or ChatGPT
- Check which MCP servers are compatible with your specific AI client
- Evaluate whether an MCP server is maintained before depending on it in production
- Get the correct install command for any MCP server without digging through READMEs
- Discover MCP servers by category: databases, browsers, dev tools, APIs, and more
- Maintainers: claim your server, correct the listing, and control how it appears
- Maintainers: earn a Verified badge and a do-follow backlink by passing a live handshake test
- Compare alternatives to a broken or abandoned MCP server via tool-level pages
- Monitor whether your own server still passes verification (weekly automated re-checks)
Comments
MCPVault started with one news headline. When Smithery.ai got acquired in early August, the MCP ecosystem suddenly lost its most used independent directory. Over 10,000 public MCP servers, and no neutral place to find quality ones. I had just finished building The Director (a retro AI-run listing site) and realized I already had the infrastructure to do this properly. So I built MCPVault in a single day. The core idea is simple: every public MCP server on GitHub is already in the vault. Developers can search, filter, and discover servers right now. But each listing starts as "stale" until the actual creator claims it, fills in real details, and optionally goes through live verification (a real MCP handshake, not just a checkbox). Claimed and verified servers get a do-follow backlink, which matters a lot for open source maintainers trying to build visibility. We currently have just under 5,000 servers indexed, with 26,000+ individual tool sub-pages that are already being crawled by Google. The verification system launched two days after the site went live, and directree-mcp was the first verified server. If you build MCP servers or work with AI agents, I would love to hear what you think is missing from the directory experience today.
