Cmd line mcp mcp server connects Cmd Line MCP to AI assistants that speak the Model Context Protocol. An MCP server that lets AI assistants run terminal commands safely. Commands are categorized (read/write/system), directories are whitelisted, and dangerous patterns are blocked automatically.
An MCP server that lets AI assistants run terminal commands safely. Commands are categorized (read/write/system), directories are whitelisted, and dangerous patterns are blocked automatically.
The server is distributed via PyPI as cmd-line-mcp, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
The server reads 2 environment variables: CMD_LINE_MCP_SECURITY_REQUIRE_SESSION_ID, CMD_LINE_MCP_COMMANDS_READ. Keep credentials in your client's env block or a secrets manager rather than committing them.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Cmd Line MCP sits in that group. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
