guMCP is an open-source collection of Model Context Protocol (MCP) servers that can be run both remotely and locally. The project aims to create the largest collection of MCP servers with a unified backend, fostering a community around AI integrations and the future of AGI.

While many MCP server providers are closed source, and open-source alternatives typically only support local hosting through stdio, guMCP provides:

• A comprehensive collection of MCP servers that work both locally and remotely
• Support for both stdio and SSE (Server-Sent Events) transports
• A unified backend architecture for consistent implementation
• Full open-source access to encourage community contributions

• Dual Transport Support: All servers support both:

  • Local hosting through stdio
  • Remote hosting through SSE

• Unified Backend: Consistent implementation patterns across all servers

• Extensive Server Collection: Including servers for:

  • File systems and databases
  • Development tools
  • Web and browser automation
  • Productivity and communication
  • AI and specialized tools

1. Clone the repository:

git clone https://github.com/gumloop/guMCP.git
cd guMCP

2. Create and activate virtual environment:

python -m venv venv
source venv/bin/activate  # On Unix/macOS
venv\Scripts\activate     # On Windows

3. Install dependencies:

pip install -r requirements.txt
pip install -r requirements-dev.txt

4. Set up environment variables:

cp .env.example .env  # Then edit with your configuration

python src/servers/local.py --server=simple-tools-server

For convenience, we also provide a lightweight MCP Client to start and connect to stdio servers. Usage:

 python tests/clients/LocalMCPTestClient.py --server=simple-tools-server

An SSE server can be run locally. This will provide a single URL and host every server available.

To start the SSE development server, run:

./start_remote_dev_server.sh

For convenience, we also prove a lightweight MCP Client to connect to SSE servers. Usage:

python tests/clients/RemoteMCPTestClient.py --endpoint=http://localhost:8000/simple-tools-server/local
