Are MCP servers safe to connect to my AI?
Not automatically. An MCP server's tool descriptions are read by your AI as instructions, so a malicious or careless server can hide prompt injection in them, ship destructive tools without warning labels, or leave out the safety annotations clients rely on. Check a server before connecting it. sebbi.pro grades every remote server in the official registry automatically and seals each grade.
How it works
- Look up the server's grade at sebbi.pro/mcp-servers, or check any server free with MCP Shield.
- Watch for tools that can delete, pay or send without a destructive warning.
- Prefer servers whose tools carry read-only and destructive annotations.
- Put the server behind Sealed MCP so every tool call your AI makes leaves a receipt.
