How to Set Up and Use Experimental Ext Skills
Experimental Ext Skills is a working group incubation project from the Model Context Protocol organization that explores how to discover, distribute, and manage structured workflow instructions (called 'skills') through MCP's existing Resources primitive. Rather than hardcoding capabilities into MCP servers, the proposal allows skills to be served dynamically so AI agents can discover what workflows are available at connection time without client-side re-configuration. The project is maintained by the Skills Over MCP Working Group and is primarily a design and specification effort, with reference implementations intended to inform future MCP standards around enterprise skill distribution and RBAC.
Prerequisites
- Familiarity with the Model Context Protocol (MCP) specification
- Node.js 18+ for running any reference TypeScript implementations
- An MCP-compatible client such as Claude Desktop or Claude Code for testing
- Git for cloning the repository and following specification development
Clone the repository
Clone the experimental-ext-skills repository to explore the specification documents and any reference implementations provided by the working group.
git clone https://github.com/modelcontextprotocol/experimental-ext-skills.git
cd experimental-ext-skillsReview the SEP-2640 specification
The core design is captured in SEP-2640 and associated pull requests. Read the proposal documents in the repository to understand the skills-over-MCP architecture before running any reference implementation.
Install dependencies for any reference TypeScript server
If the repository includes a reference TypeScript implementation, install its dependencies and build it.
npm install
npm run buildConfigure a local MCP client for testing
Add the experimental skills server to your Claude Desktop or Claude Code configuration to test skill discovery. The exact command will depend on the reference implementation provided in the repository.

}
}
}Contribute or follow the working group discussion
This is an active specification project. Join the MCP Discord channel to participate in design discussions or open a pull request to contribute to the spec.

Conceptual prompts for exploring skills discovery once connected to a skills server.
- "List all available skills on this MCP server"
- "What workflow skills are available for data processing?"
- "Show me the steps for the onboarding skill"
- "Execute the weekly-report skill with these parameters"
- "Which skills do I have permission to run?"Troubleshooting Experimental Ext Skills
No tools or resources appear when connecting with an MCP client
This project is experimental and in active specification development. The repository may contain design documents rather than a fully functional server. Check the repository's README and open issues for the current implementation status before expecting runnable tools.
npx experimental-ext-skills fails with package not found
The package may not yet be published to npm. Clone the repository from https://github.com/modelcontextprotocol/experimental-ext-skills, install dependencies with npm install, and run the server locally with node dist/index.js or the command specified in the package.json scripts.
