What is MCP Terminal Server?
The MCP Terminal Server is a server that executes shell commands securely using the Model Context Protocol (MCP). It provides controlled command execution with security features and resource limits, preventing command injection and resource exhaustion.
How to use MCP Terminal Server?
To use the MCP Terminal Server, you need to install it and configure it with an MCP-compatible client like Claude Desktop. The server can be installed using uv pip install mcp-terminal. You then configure the client to communicate with the server using the MCP protocol, specifying allowed commands, timeouts, and output size limits.

MCP is a protocol for communication between applications, enabling them to share context and execute commands securely.
How do I secure the MCP Terminal Server?
How do I secure the MCP Terminal Server?
Configure the allowed-commands setting to restrict which commands can be executed. Also, use conservative timeout and size limits.
What happens if a command exceeds the timeout?
What happens if a command exceeds the timeout?
The command execution will be terminated, preventing the server from hanging.
What happens if a command produces too much output?
What happens if a command produces too much output?
The output will be truncated to the maximum allowed size, preventing memory exhaustion.
How do I test the MCP Terminal Server?
How do I test the MCP Terminal Server?
You can use the MCP Inspector tool or run the included pytest tests.
