ShellAgent

ShellAgent is an MCP server that provides terminal command execution capabilities to AI clients and coding assistants. It connects Model Context Protocol hosts directly to the host operating system's command-line environment, allowing tools to run terminal instructions, scripts, and administrative tasks. Designed for software developers, DevOps engineers, and system administrators, ShellAgent enables workflows where language models can execute build commands, navigate file trees, run test suites, and inspect system output without manual context switching. The package can run via standard input/output (stdio), operate as a remote server utilizing Server-Sent Events (SSE) or streamable HTTP endpoints, or be loaded as an in-memory transport module within JavaScript and TypeScript applications. By serving as an intermediary between language models and the shell, ShellAgent allows agents in IDEs and desktop environments to troubleshoot runtime issues, automate routine developer operations, and inspect local project environments programmatically.

How to install and configure ShellAgent

To install and register ShellAgent, ensure Node.js 18 or newer is installed on your machine. You can configure the server in your MCP client (such as Claude Desktop, Cursor, or Windsurf) using the following steps: 1. Open your client's MCP configuration settings file. 2. Add the shellagent-mcp entry under mcpServers using standard input/output: json { "mcpServers": { "shellagent-mcp": { "command": "npx", "args": [ "mcp-server-shellagent-mcp@latest" ] } } } 3. Alternatively, if using the VS Code CLI, execute: code --add-mcp '{"name":"shellagent-mcp","command":"npx","args":["mcp-server-shellagent-mcp@latest"]}' 4. Restart your MCP client to enable the server tools.

What you can do with ShellAgent

• Running software builds, compilation steps, and automated testing suites directly from coding assistants inside VS Code or Cursor. - Executing routine Git version control commands like status checks, branching, and diff reviews through conversational prompts. - Inspecting file directory contents, reading system configurations, and verifying environment variable setups across local environments. - Automating continuous integration and deployment scripts on remote systems using Streamable HTTP or SSE endpoints. - Integrating programmatically into custom TypeScript or JavaScript agent applications using in-memory transport bindings without external CLI installs.

Part of MCP Servers

What are the requirements to run ShellAgent?

ShellAgent requires Node.js version 18 or newer installed on your machine. It also requires an MCP-compatible client such as VS Code, Cursor, Windsurf, Claude Desktop, or any custom client built with the Model Context Protocol SDK.

How do I install ShellAgent?

You can run ShellAgent directly using npx by configuring mcp-server-shellagent-mcp@latest as the executable command in your MCP client settings. For VS Code, you can also register it via the command line using the code --add-mcp flag.

Can ShellAgent be accessed remotely?

Yes, ShellAgent can run as a remote server using Server-Sent Events or Streamable HTTP. You launch the server with npx mcp-server-shellagent-mcp --port followed by your chosen port, then connect your MCP client to the resulting endpoint.

Is ShellAgent open source?

Yes, ShellAgent is an open-source project. The code repository is hosted on GitHub under myshell-joe/Shellagent-MCP, where users can review the implementation, report issues, and follow development updates.
