Follow these steps to run the MCP server as a Meshagent tool in the cloud:

  1. Install Meshagent

    pip install "meshagent[all]"

  2. Authenticate

  3. Start the MCP Service in a Meshagent Room

    meshagent service test --room=test --role=agent --image=meshagent/mcp-pulumi:latest --env MESHAGENT_PORT=8001  --port="num=8001 path=/webhook liveness=/ type=meshagent.callable" --name=mcp-pulumi-service
    • This command starts a Meshagent room with the MCP server available. Rooms automatically close if left inactive.

  4. Join Room & Use Pulumi Toolkit with a Chatbot

    meshagent chatbot join --room=test --agent-name=sample --name=sample --toolkit=mcp-pulumi
    • Starts a chatbot in the Meshagent room enabled with the Pulumi toolkit. You can attach multiple toolkits to the same agent in a room.
    • The output will include a link to the room UI where you can interact with the agent and tools.
