Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Basic MCP Server read the file /tmp/data.json"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
A small MCP server built with the official
Python SDK (mcp 2.x). It exposes four tools that let an MCP client
(Claude Desktop, the MCP Inspector, etc.) work with the local file system,
run shell commands, and fetch web pages.
Tool | Description | Parameters |
| Reads the file at the specified path. |
|
| Creates a new file and writes the given content into it. Overwrites the file if it already exists. |
|
| Runs the given shell command and returns its output (stdout + stderr). |
|
| Fetches a URL with an HTTP GET request and returns the status code and the page source. |
|
All tools return plain strings. Failures are prefixed with ERROR:, successful
writes with INFO:.
Warning:
execute_commandruns arbitrary shell commands with the permissions of the user running the server. Only connect clients you trust.
