Email MCP servers, with their tools checked
Every server in the official MCP registry that mentions Email, with a public endpoint, read the way an MCP client reads it and checked for tool poisoning. The list updates as the registry does, and each server is read again every week.
516 listed. We have read the tools of 68 so far; the others want credentials first, could not be reached, or are still waiting for their first read. Showing the first 200, servers whose tools we could read first.
These servers act inside an account you own, usually with a token you give them. Prefer the narrowest access the tools need, and check which tools can send, post or delete.

Choosing one
Open a server's page to see the tools it advertises, whether it sets instructions for the model, and our latest read. Here, 67 of the servers shown matched none of our tool-poisoning rules on their last read. A clean read means our rules found nothing, not that a server is harmless; still check what access it asks for. To check one that is not listed, paste its URL into the free MCP server check.
