Mattermost Plugin Agents

Mattermost Agents is the AI capability for the Mattermost collaboration platform, presented on the Mattermost Sovereign AI page. It brings LLM features into team chat while keeping collaboration data inside the organization's own network and deployment. Teams can run local models through Ollama, vLLM or any OpenAI compatible API, or connect cloud providers including OpenAI, Anthropic, Azure and Bedrock, which avoids lock in to a single model vendor. Capabilities listed on the page include direct chat with agents, tagging an agent in any conversation, natural language search, smart reactions, channel summaries, meeting summaries and action item extraction from threads, channels and recordings. Agents can also be used inside Mattermost Playbooks. For integration, agents connect to existing tools through MCP, can search Mattermost and operate Playbooks, and require user approval before tools run. Governance features include tool approval governance, attribute based access control, service account agents, custom MCP connectors, an MCP platform for plugins and token accounting. It is aimed at security conscious and regulated organizations that already run Mattermost, including government, financial services, healthcare, energy and critical infrastructure teams that care about data sovereignty. Mattermost does not publish list prices for the plans that carry these features. The pricing page shows Professional with a contact sales button, Enterprise with a get pricing button and Enterprise Advanced as request a quote, with the agentic platform, bring your own and multi LLM integration, an agent control plane and agents token accounting listed among the features. A free limited use edition of Enterprise Advanced is offered for technical evaluation, and a one hour trial environment is available.
