Dead
Every channel of this server has been unreachable for long enough to be marked dead. Its trust score is pinned to 0 and does not recover automatically: even once the server responds again it stays dead until it is manually reinstated.
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →
Endpoint Security0
- TLS not yet verified: we couldn't open a connection to check the certificate. View diagnostics → Unverified
- Authorisation not yet verified: we couldn't confirm whether this endpoint requires it. View diagnostics → Unverified
- HTTPS enforcement could not be verified: this endpoint is not published over https, so there is no plaintext variant to compare against. View diagnostics → Unverified
- HSTS not yet verified: we couldn't read the response headers to check for it. View diagnostics → Unverified
- DNSSEC not yet verified: we couldn't validate it against a resolver. View diagnostics → Unverified
Transport & Reachability0
- Transport check failed: declared streamable-http, but we couldn't connect to verify it. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability0
- Schema not yet verified: we couldn't read the endpoint's schema.Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0

Unverified: 5 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.
How do I install the MailFathom MCP server?

What is the MailFathom MCP server?
MailFathom is an MCP server listed in the public MCP registry as io.github.Krzysztof318/mailfathom. Security-first, self-hosted email archive with search, cited answers, and sending for AI agents. This page covers its hosted endpoint (https://{mailfathom_host}/mcp).
Is the MailFathom MCP server safe to use?
MailFathom scores 0 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
Does the MailFathom MCP server require authentication?
Its publisher declares no required credentials for MailFathom. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.
Is the MailFathom MCP server still maintained?
MailFathom has been unreachable for long enough that we treat it as dead, and its score is pinned to zero. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
