- 1Install in one click
Pick Mattermost from the marketplace. WorkAist handles Personal Access Token and stores the credentials encrypted — no JSON keys to paste.
- 2Tools auto-generated
Mattermost exposes 6 MCP tools to every agent in your workspace: send_message, list_channels, search_messages, get_thread, and more. Each tool is a typed function, not a brittle script.
- 3Data flows to your graph
Historical communication records sync to your private knowledge graph. Agents query relationships across all connected sources, not just Mattermost 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 Mattermost call.
Mattermost is communication 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. Mattermost authenticates via a personal access token, and because WorkAist is self-hosted under AGPL-3.0, your data never leaves your own infrastructure.
Authentication & setup
The Mattermost connector authenticates via Personal Access Token.
Create a token in the service's developer settings with read+write scopes, paste it once at install time. Stored encrypted.

FAQ
Can a WorkAist AI agent really automate Mattermost 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 Mattermost API directly?▼
The connector adds permission isolation, audit logging, cost tracking per agent, and reversible PII redaction at the LLM boundary. It also presents Mattermost 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 Mattermost's own API costs (if any) and the LLM tokens your agent consumes.
Is my Mattermost data sent to a third party?▼
No. WorkAist runs in your own infrastructure. Data flows from Mattermost → your WorkAist instance → the LLM you choose. Sensitive fields can be tokenized before reaching the LLM.
What if Mattermost changes its API?▼
The connector is versioned and published openly. When Mattermost ships breaking changes, we bump the connector version and the marketplace UI surfaces the upgrade as a one-click apply.
