If you use docker you can run the command docker build -t mcp-node . and then the following command:
docker run --name mcp-node-container -p 8002:8002 \
-e MCP_TRANSPORT=http \
-e LOG_LEVEL=debug \
mcp-node
Using NestJS:
Run npm run start:dev to view logs and make changes dynamic.
Another option is to run npm run build and then npm run start:prod to run the compiled product.
Test your MCP
Run the command npx @modelcontextprotocol/inspector to visualize something like this:
