Works with Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This connection provides 12 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.

Finding that single decision point in old chat logs shouldn't take 20 minutes of scrolling.

Right now? You gotta log into Mattermost. Then you click the channel, scroll up past days of general chatter, find the correct date range, and manually copy-paste snippets to a ticket or document. It's tedious, and chances are, you miss something crucial.

With this MCP server, your agent handles all that grunt work. You just tell it: 'What was decided about API rate limits last month?' And BAM—it runs `list_channel_posts` and hands you the clean summary right back in chat. No clicking, no scrolling.

Mattermost MCP Server: Manage team communication from your AI client.

The old way meant opening a browser tab just for Mattermost. If you needed to check if the DevOps team had assigned the patch, you'd switch context entirely—leaving your IDE or ticketing system behind.

Now, your agent can run `list_channel_posts` right where you are working. It pulls the chat data into the conversation flow instantly. The workspace becomes part of your workflow, not a separate tab.

What your AI can actually do with this

You've got full control over your team chat, period. This server lets your agent talk directly to Mattermost—you manage everything from sending quick messages in DMs to tracking deep deployment threads and listing out every user on the whole platform. It gives your agent read access, write access, and management tools for your entire workspace history.

Messaging and Channels

When you need to communicate, your agent sends a new chat message using post_message to any channel or direct message recipient. You can pull up the full conversation record from an entire channel at any time by calling list_channel_posts, which retrieves the complete chronological list of posts and messages. If the team needs more space, your agent establishes a dedicated discussion area using create_new_channel.

For keeping tabs on existing groups, you can get a definitive rundown of every single channel belonging to a specific group via list_team_channels.

User and Team Management

Need to know who’s on the roster? You'll get a complete list of every user account registered on the server using list_server_users, which includes details about their roles and current status. Want to check your own credentials? Your agent pulls your personal profile info with get_my_profile. For structuring teams, you can retrieve a comprehensive list of all major teams defined in the workspace hierarchy via list_teams.

Once you pick a specific team, you get granular details about it using get_team_details. The system also lets you see every possible access role and permission set up within Mattermost by listing out available roles with list_system_roles.

System Status and Configuration

Before trusting your agent with anything important, you'll want to check the connection. Running test_server_ping gives a quick health check confirming the API link is live. If you need to know how things are configured, get_server_config retrieves all the current system settings and operational parameters for the entire Mattermost instance.

For visibility into automated actions, your agent can display every incoming webhook setup by listing them with list_incoming_webhooks. These tools ensure you see exactly what's running behind the scenes.

Questions you might have

How do I use list_channel_posts with Mattermost? +

You prompt your agent to run list_channel_posts and specify the channel ID or name. The tool returns a chronological list of messages, allowing you to read through history without manually scrolling.

Can I use post_message to automate alerts? +

Yes, absolutely. You can instruct your agent to run post_message immediately after a script finishes. This is perfect for notifying the #alerts channel that a deployment succeeded or failed.

What if I need to know who has access to certain features? Do I use list_server_users? +

While list_server_users gives you names, run list_system_roles first. This shows all available permissions, and then you can ask your agent about specific user roles.

Does Mattermost MCP Server support reading DMs? +

Yes. You can use the message tools to read and reply in private channels (DMs). Just specify the recipient's ID or name when you talk to your agent.

How do I check if my Mattermost connection is active before running any commands? Do I use test_server_ping? +

Yes, run test_server_ping to verify the API health. This immediately confirms your agent can talk to the server without needing complex setup or triggering rate limits.

If I need to audit which services are sending data into Mattermost, what tool should I use? Is it list_incoming_webhooks? +

You use list_incoming_webhooks to view event configurations. This lets your agent check exactly which external services are feeding data and what triggers are active in the workspace.

How can my AI client understand the different levels of access or permissions on the server? Should I use list_system_roles? +

Run list_system_roles to see every available access role. This gives your agent a clear view of the permission hierarchy—like Admin vs. Member—so it doesn't attempt actions users can't perform.

Before creating new groups, how do I get an overview of all organizational units? Do I use list_teams? +

Use list_teams to retrieve a list of every defined team in your workspace. This is crucial for structuring automation; your agent knows which group containers exist before managing channels inside them.

Can I read messages and reply to threads? +

Yes. Browse channel history, read specific threads, and post replies or new messages with markdown formatting.

How does Mattermost authentication work? +

Mattermost requires your instance's Base URL and a Personal Access Token for Bearer authentication.

Can I manage channels and users? +

Yes. Create new public/private channels, invite users, and check their online status.
