Dockerise the MCP Run Python server (#1837)

[rohit133]

Summary

This adds Docker support for the MCP Run Python server and sets up automated Docker image publishing via GitHub Actions.

Changes

Dockerfile:

• Adds a Dockerfile to run the MCP Run Python server using the official Deno image.
• Default command runs the server in SSE mode on port 3101, suitable for MCP client integration.

GitHub Actions Workflow:

• Adds docker-publish.yml to build and publish the Docker image to Docker Hub (or another registry) on push to main.
• Requires DOCKERHUB_USERNAME and DOCKERHUB_TOKEN secrets to be set in the repository.

Test Client:

• Adds test_mcp_client.py to verify the server is running and can execute Python code via the MCP protocol.

How to test

1. Build and run the Docker image:

docker build -t mcp-run-python ./mcp-run-python
docker run -d -p 3101:3101 mcp-run-python

2. Run the test client:

python3 mcp-run-python/test_mcp_client.py

You should see:

<status>success</status>
<output>
   hello world
</output>

I think we can publish the images on github instead of dockerhub.

I have updated it to publish the images on GitHub.
