Overview

What is STeLA MCP?

STeLA (Simple Terminal Language Assistant) MCP is a lightweight Python implementation of a Model Context Protocol server that provides secure access to local machine commands and file operations via a standardized API interface. It acts as a bridge between applications and the local system, implementing the MCP architecture.

How to use STeLA MCP?

Install via Smithery (npx -y @smithery/cli install @Sachin-Bhat/stela-mcp --client claude) or manually by cloning the repository, creating a virtual environment, and installing dependencies. Configure environment variables for directory access (ALLOWED_DIRS, ALLOWED_DIR), command security (ALLOWED_COMMANDS, ALLOWED_FLAGS, MAX_COMMAND_LENGTH, COMMAND_TIMEOUT), then start the server with uv run python -m src.stella_mcp.server. Use with Claude Desktop by adding it as an MCP tool.
