Enables Model Context Protocol (MCP) integration for secure shell command execution, allowing large language models to run commands and receive combined output and return codes efficiently.
Unlock the full potential of Shell MCP Server through LangDB's AI Gateway. Get enterprise-grade security, analytics, and seamless integration with zero configuration.
Free tier available • No credit card required
A Model Context Protocol server that provides shell command execution capabilities. This server enables LLMs to execute shell commands and receive their output in a controlled manner.

no specific installation is needed. We will
use uvx
to directly run mcp-server-shell.
Alternatively you can install mcp-server-shell
via pip:
pip install mcp-server-shell
After installation, you can run it as a script using:
python -m mcp_server_shell
Add to your Claude settings:
Using uvx
"mcpServers": { "shell": { "command": "uvx", "args": ["mcp-server-shell"] } }
Using pip installation
"mcpServers": { "shell": { "command": "python", "args": ["-m", "mcp_server_shell"] } }
Add to your Zed settings.json:
Using uvx
"context_servers": { "mcp-server-shell": { "command": "uvx", "args": ["mcp-server-shell"] } },
Using pip installation
"context_servers": { "mcp-server-shell": { "command": "python", "args": ["-m", "mcp_server_shell"] } },
Execute a shell command:
{ "name": "execute_command", "arguments": { "command": "ls -la" } }
Response:
{ "command": "ls -la", "output": "total 24 drwxr-xr-x 5 user group 160 Jan 1 12:00 . drwxr-xr-x 3 user group 96 Jan 1 12:00 ..", "return_code": 0 }
You can use the MCP inspector to debug the server. For uvx installations:
npx @modelcontextprotocol/inspector uvx mcp-server-shell
Or if you've installed the package in a specific directory or are developing on it:
cd path/to/servers/src/shell npx @modelcontextprotocol/inspector uv run mcp-server-shell
⚠️ Warning: This server executes shell commands directly on your system. Use with caution and implement appropriate security measures to prevent unauthorized or dangerous command execution.
We encourage contributions to help expand and improve mcp-server-shell. Whether you want to add new features, enhance security, or improve documentation, your input is valuable.
