Set Up a Virtual Environment

uv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
# On fish shell - source .venv/bin/activate.fish

Install Required Packages

uv sync

Configure Mattermost Settings

Create a .env file with your Mattermost and MCP server settings:

MATTERMOST_URL=http://localhost:8065
MATTERMOST_TOKEN=your-bot-token
MATTERMOST_SCHEME=http
MATTERMOST_PORT=8065
MATTERMOST_TEAM_NAME=your-team-name
MATTERMOST_CHANNEL_NAME=town-square
MCP_COMMAND=python
MCP_ARGS=mcp_server.py
LOG_LEVEL=INFO

Configure MCP Servers

Edit mcp-servers.json to define your MCP servers:

{
    "mcpServers": {
      "ollama-mcp-server":{
        "command": "python",
        "args": ["ollama-mcp-server/src/ollama_mcp_server/main.py"],
        "type": "stdio"
      },
      "simple-mcp-server": {
        "command": "python",
        "args": ["simple-mcp-server/server.py"],
        "type": "stdio"
      },
      "mattermost-mcp-server": {
        "command": "python",
        "args": ["mattermost-mcp-server/src/mattermost_mcp_server/server.py"],
        "type": "stdio"
      }
    }
}

Start the Mattermost MCP Client

python src/mattermost_mcp_client/main.py

💡 Key Use Cases in AI Workflows

Real-World Scenario 1: Collaborative Tool Usage

In a software development team using Mattermost, developers can quickly run code analysis tools provided by an MCP server. The integration allows real-time updates and feedback within the chat interface, enhancing productivity.

!mcp mattermost-mcp-server call post-message {"channel_id": "5q39mmzqji8bddxyjzsqbziy9a", "message": "Hello from Demo!"}

Real-World Scenario 2: Prompt Generation

A marketing team might use the Mattermost MCP Client to generate creative prompts for brand content. Commands like !mcp ollama-mcp-server call generate could provide new ideas based on user input, streamlining the creativity process.

!mcp ollama-mcp-server call generate {"prompt": "Write a short poem about AI", "model": "llama3.2:latest"}

🔌 Integration with MCP Clients

The Mattermost MCP Client supports integration with several MCP clients, including:
