Fastmail Blade uses **JMAP**, Fastmail's native protocol:\n\n- **JMAP-native** — stateless, JSON-based, supports batch operations natively. No IDLE hacks, no MIME parsing, no connection state management.\n- **Masked Email** — full CRUD for Fastmail's privacy aliases (create, list, enable/disable). No IMAP MCP can touch this — it's a Fastmail extension that only exists in JMAP.\n- **Push notifications** — real-time EventSource via JMAP Push. Know when mail arrives without polling.\n- **Incremental sync** — JMAP state tokens for delta changes. Get only what's new since your last check, not the entire mailbox.\n- **Token-efficient** — concise pipe-delimited output, null-field omission. IMAP MCPs dump raw headers and MIME multipart.\n- **Write-safe** — env-gated writes, batch limits (50 max), credential scrubbing on all error paths.\n\n## Features\n\n- **18 tools**: email read/write/manage, masked email, push notifications, meta\n- **Masked Email management** — no other MCP server exposes this Fastmail extension\n- **JMAP Push (EventSource)** — real-time state change notifications\n- **Write-gate** — all write operations disabled by default (`FASTMAIL_WRITE_ENABLED=true`)\n- **Token-efficient** — concise output, capped lists, null-field omission\n- **Batch limits** — `mail_bulk` capped at 50, `mail_search` defaults to 20\n- **SKILL.md** — self-teaching instructions for Claude\n\n## Requirements\n\n- macOS (tested) or Linux\n- Python 3.12+\n- [uv](https://docs.astral.sh/uv/)\n- Fastmail account with API to…","publisher":{"name":"Piers","url":null},"homepage":null,"repository":null,"version":"0.6.0","license":"MIT","protocols":["mcp"],"tags":["email","fastmail","jmap","masked-email","mcp"],"pricing":null,"endpoints":[{"url":"pypi:fastmail-blade-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","license":"pypi","summary":"pypi","version":"pypi","description":"pypi","publisherName":"pypi"}},"derived":{"capabilities":[{"slug":"productivity.email","name":"Email","confidence":1,"provenance":"declared"},{"slug":"communication.notifications","name":"Notifications","confidence":0.825,"provenance":"derived"}],"categories":["communication","productivity"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"fastmail-blade-mcp","registry":"pypi","observedAt":"2026-10-28T00:27:49.267Z","publishedAt":"2026-06-11T17:26:51.532684Z","latestVersion":"0.6.0"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"fastmail-blade-mcp","url":"https://pypi.org/project/fastmail-blade-mcp/","firstSeenAt":"2026-09-09T15:22:29.599Z","fetchedAt":"2026-10-28T00:26:57.263Z","normalizedAt":"2026-10-28T00:26:57.263Z"}]},"firstSeenAt":"2026-09-09T15:22:29.599Z","updatedAt":"2026-10-28T00:27:49.267Z"}
