What io.github.alunsoldantarctica/mail-index does

mail-index downloads a preview of your whole inbox to your machine, then smartly fetches the full text of the messages that matter as you use it. That local index lets your AI agent run true summarization and recall over your entire mailbox — instead of being trapped behind Gmail's search bar.

mail-index

mail-index downloads a preview of your whole inbox to your machine, then smartly fetches the full text of the messages that matter as you use it. That local index lets your AI agent run true summarization and recall over your entire mailbox — instead of being trapped behind Gmail's search bar.

It works through a local MCP server, so any agent (Claude, Codex, any MCP client) can query it. Local-first — the index never leaves your machine. Read-only by default — it never sends or mutates your mail unless you explicitly opt into archive + label edits (a least-privilege gmail.modify re-auth; never send or delete). See ADR-0007.

_{Ask a vague question → one local MCP call → ranked, snippet-first answer.
Interactive version →}

Status: v1.0 — published. Progressive sync, the correspondence graph, the interest engine, curation, the full 23-tool MCP surface, and the write-back loops are built and tested — and mail-index is live on npm with a .mcpb bundle. Still in progress: the bundled Option A OAuth client and signed one-click installers. Architecture lives in docs/PLAN.md; start with docs/INSTALL.md.

[!TIP] New in v1.4 — opt-in mailbox writes + human-readable labels. mail-index can now archive a message and edit its labels directly on Gmail — via the archive / label CLI commands and the archive_message / modify_labels MCP tools, on both the gog and gws adapters. It stays read-only by default: writes are unreachable until you opt in with a least-privilege gmail.modify grant (never send or delete) — enable per account with mail-index setup --account <email> --enable-writes or the bundled scripts/enable-writes.sh. Labels now render as their human names everywhere (the index caches Gmail's label catalogue and resolves Label_3546… → "Expedition Insure" in both directions), and you can pass a friendly label name to label --add/--remove. The local-only / zero-egress guarantee is unchanged. See ADR-0007.

How it works

Progressive sync — metadata for the whole mailbox in minutes; bodies fetched selectively.
Graph — contacts, domains, threads; centrality + communities over your human (non-bulk) mail.
Interest — an engagement score per contact from read/reply/star/importance signals. A seed for your curation, not an autonomous decision.
Curate — you (via your agent, or a CLI wizard) confirm who/wh
