Pick Fastmail from the marketplace. WorkAist handles HTTP Basic auth and stores the credentials encrypted — no JSON keys to paste.
- 2Tools auto-generated
Fastmail exposes 6 MCP tools to every agent in your workspace: list_emails, send_email, search_inbox, get_thread, and more. Each tool is a typed function, not a brittle script.
- 3Data flows to your graph
Historical email records sync to your private knowledge graph. Agents query relationships across all connected sources, not just Fastmail in isolation.
- 4Your agents take action
Your AI agent picks the right tool, runs it under your access policies, and answers in plain language — with a full audit trail of every Fastmail call.
Fastmail is email software you can connect to WorkAist in minutes. Through the open MCP standard, your AI agents triage messages, draft replies and route conversations to the right person — autonomously, under explicit permissions, with no manual hand-offs. Fastmail authenticates via username and password, and because WorkAist is self-hosted under AGPL-3.0, your data never leaves your own infrastructure.
Authentication & setup
The Fastmail connector authenticates via HTTP Basic auth.
For self-hosted or legacy services. Use an app password when the provider supports them.

FAQ
Can a WorkAist AI agent really automate Fastmail end-to-end?▼
Yes. The connector exposes read and write tools through Model Context Protocol. AI agents call them through plain-language instructions in a CLAUDE.md file — no glue code.
How does this differ from using the Fastmail API directly?▼
The connector adds permission isolation, audit logging, cost tracking per agent, and reversible PII redaction at the LLM boundary. It also presents Fastmail as part of a unified Knowledge Graph alongside your other tools.
What does it cost?▼
WorkAist is open-source under AGPL-3.0 and self-hosted, so the connector itself is free. You pay only for Fastmail's own API costs (if any) and the LLM tokens your agent consumes.
Is my Fastmail data sent to a third party?▼
No. WorkAist runs in your own infrastructure. Data flows from Fastmail → your WorkAist instance → the LLM you choose. Sensitive fields can be tokenized before reaching the LLM.
What if Fastmail changes its API?▼
The connector is versioned and published openly. When Fastmail ships breaking changes, we bump the connector version and the marketplace UI surfaces the upgrade as a one-click apply.
