About MCP or Not
AI assistants can now work inside the tools you use, through MCP servers and Claude connectors. But search for any product plus “MCP” and you get registries listing dozens of servers with no way to tell which one the vendor actually stands behind. MCP or Not gives one dated, sourced answer per tool.
How we check
Every verdict cites primary evidence: the vendor’s documentation, a repository owned by the vendor, or the connector directory. A registry listing on its own never makes something official. Each page shows the date we last checked it.
- OfficialThe vendor publishes the server or connector, and its own docs or repo confirm it.
- Community onlyCredible third-party servers exist, but we found nothing from the vendor.
- Via a bridge onlyReachable only through an intermediary such as Zapier or Composio.
- Not verifiedNot enough reliable evidence either way. This never means the vendor has no MCP support.
The safety check
Five checks on every main integration: whether the publisher is verified, how it signs in, whether it can write or delete by default, whether its tool descriptions contain instructions aimed at the AI, and whether the repository is maintained. The MCP security guide explains each one.
Independence
We are not affiliated with any vendor we cover. Vendors cannot pay to change a verdict. If we ever show a sponsor or a referral link, it will be clearly labeled and kept apart from the verdict.
