What does this entry provide?

io.github.iancollins27/mailsnail is an MCP server entry in ChatHome Skills, sourced from Official MCP Registry and scored 67/100.

ChatHome Skills discovered this entry through its daily ingest of official registries and GitHub discovery queries, and re-verifies repository facts, freshness signals, and install metadata on every run. The quality score weighs official-registry presence, a working install command, license clarity, GitHub star trajectory, and repository freshness — the full formula is on the Sources page.
