You can run and expose arbitrary command-line tools through a configurable MCP server. By defining tools in a JSON configuration, you gain secure, controlled access to specific utilities while enforcing parameter validation, directory restrictions, and timeouts.

How to use

You interact with the MCP server through your client by calling predefined tools. Each tool is defined in configuration with a name, a description, the command to execute, and any required parameters. You can ask your MCP client to list files, search through code, count lines, or perform other supported actions without exposing your entire system.

How to install

Prerequisites you need before installing: Node.js (runtime), npm for package management, and a local development environment for editing configuration files.

Create your project directory and install dependencies.
Build the TypeScript code.
Define your tools in a JSON configuration file named tools.json.
Point your client to the MCP server using the local stdio configuration described below.

Configuration and usage notes

The MCP server is configured to execute tools defined in tools.json. Each tool includes command arguments and optional environment variables. Execution is isolated by directory restrictions, parameter validation, and timeouts to prevent abuse.

Environment variables shown in the example configure how the MCP server locates its tool definitions and runs in your environment.

Security and reliability considerations

Parameter validation ensures inputs match expected types and formats.
Directory scoping restricts where tools can operate to protect your filesystem.
Timeouts prevent long-running or stalled commands from consuming resources.

Available tools

list_files

List directory contents for a given path with optional flags to show hidden files or detailed details.

grep_search

Search for a pattern within files, returning matches with file paths and line numbers.

word_count

Count lines, words, or characters in input files or streams.

git_status

Show the current status of a Git repository, including staged and unstaged changes.

find_files

Find files by pattern or name across a directory tree.
