MCPGod

Fine-grained control over model context protocol (MCP) clients, servers, and tools. Context is God.

Overview

MCPGod is a CLI tool designed to help developers manage MCP servers with speed and ease. Whether you need to add, run, list, or remove servers—or even interact with server tools—MCPGod provides a streamlined interface to handle all these tasks on Windows, macOS, or Linux.

Features

Client Management
Add, remove, and list MCP servers for specific clients.
Tool Discovery List every tool on any MCP server.
Tool Calling Run any tool on any MCP server directly from the command line.
Tool/Client Permissions Allow or block specific tools for specific clients.
Detailed Logging Log every server run from every client, with timestamps and clean output for easy debugging.

Installation

Install mcpgod globally using npm:

npm install -g mcpgod

Verify the installation:

mcpgod --version

Or run directly with npx.

npx -y mcpgod

Usage

Access the CLI with the mcpgod command (or npx -y mcpgod). Below are some common examples:

Add a Server to a Client

Add an MCP server to a client (e.g., Claude) with mcpgod add <SERVER> -c <CLIENT>:
```
mcpgod add @modelcontextprotocol/server-everything -c claude
```
Only Add Specific Tools to a Client

Only add specific tools to a client with mcpgod add <SERVER> -c <CLIENT> --tools=<COMMA_DELIMITED_LIST>:
```
mcpgod add @modelcontextprotocol/server-everything -c claude --tools=echo,add
```
List Servers for a Client

List all configured servers for a specific client with mcpgod list -c <CLIENT>:
```
mcpgod list -c claude
```
Remove a Server

Remove an MCP server from your client's configuration with mcpgod remove <SERVER> -c <CLIENT>:
```
mcpgod remove @modelcontextprotocol/server-everything -c claude
```

Run a Server

Run a server process with detailed logging with mcpgod run <SERVER>:

mcpgod run @modelcontextprotocol/server-everything
mcpgod run ./mcp-server.py
mcpgod run ./mcp-server-node.mjs

List Available Tools for a Server

Display the list of tools available on a server with mcpgod tools <SERVER>:

mcpgod tools @modelcontextprotocol/server-everything
mcpgod tools ./mcp-server.py
mcpgod tools ./mcp-server-node.mjs

Call a Specific Tool on a Server

Interact with a tool by passing key-value properties with mcpgod tool <SERVER> <TOOL> [optional parameters]:

mcpgod tool @modelcontextprotocol/server-everything add a=59 b=40
mcpgod tool ./mcp-server.py echo message=hi
mcpgod tool ./mcp-server-node.mjs echo message=hi

For a complete list of commands and options, simply run:

mcpgod --help

Logging

When running a server, mcpgod logs output to:

~/mcpgod/logs

Each log file is organized by server name and timestamped to help you trace and debug any issues that arise.

Development

mcpgod is built with the Oclif framework and uses the Model Context Protocol SDK for robust interactions with MCP servers.

Clone the repository to get started with development:

git clone https://github.com/mcpgod/cli.git
cd mcpgod
npm install

Run the CLI in development mode:

./bin/dev

Publishing

Automatic publishing is handled by the version, tag and github release workflow. A new npm version is published whenever a version bump is merged into the main branch. The workflow can also be triggered manually from the Actions tab.

To enable publishing, set the following repository secrets:

NPM_TOKEN – authentication token for npm.
GH_EMAIL and GH_USERNAME – used by the README update step.

Once the secrets are configured, pushing a new version or running the workflow manually will build the project, create a GitHub release and publish the package to npm.

Linting workflows

Before committing changes to workflows, you can lint them locally:

npm run lint:workflows

Contributing

```
git checkout -b feature/your-feature
```
Make your changes, and commit them:
```
git commit -am 'Add new feature'
