Essentials MCP server with tools for filesystem operations, shell execution, and web search.

To integrate emcp, add it to your MCP configuration file. Minimal setup with uvx:

{
  "command": "uvx",
  "args": [
    "emcp"
  ],
  "env": {}
}

You can also run it standalone with uvx or install the package from PyPI with uv:

uvx emcp

uv tool install emcp

• rg (ripgrep) in your PATH for file search.

You can configure emcp through environment variables:

• EMCP_WORKING_DIRECTORY: the directory EMCP will restrict file operations to. Defaults to CwD.

With emcp, the agent has access to a variety of file-system, shell and web tools.

All filesystem operations are restricted to the configured working directory.

• fs_pwd: Get the current working directory
• fs_stat: Get file/directory metadata (size, times, type, permissions)
• fs_list: List directory contents with size, type, and name
• fs_read: Read file contents with optional line ranges
• fs_write: Write content to a file using specified mode (w, a, etc.)
• fs_search: Search files by regex pattern using ripgrep
• fs_replace: Replace occurrences of a string in a file (precise edits)
• fs_mkdir: Create directories recursively
• fs_rm: Remove files or directories (with user confirmation for directories)

• shell_run: Execute shell commands with an interactive permission system

On first use of a command, the user is prompted to allow/deny/always allow/never allow it.

• web_search: Search the web using DuckDuckGo

While emcp enforces some restrictions, it's always safer to run MCP servers in sandboxed environments. Consider using one of:

• Containers, such as docker with a mounted external directory.
• (MacOS-only) sandbox-exec, with a profile that restricts file-system access.

Get the code:

git clone [email protected]:slezica/emcp.git

Run from source:

cd emcp
uv run emcp

Run tests:

cd emcp
uv run pytest

None. Code is knowledge. Use it for good.
