Show HN: Playground to Test Skills and MCP
mcpjam.com
There’s been a lot of debate around skills vs MCP. From what I see, there’s a growing trend of people using skills paired with MCP servers. Skills teach the agent how to use the MCP server tools and guide the agent to completing complex workflows.
We’re also seeing Anthropic encourage the use of Skills + MCP in their products. Anthropic recently launched the connectors marketplace. A good example of this is the Figma connector + skills. The Figma skill teaches the agent how to use the Figma MCP connector to set up design system rules.
The use of Skills + MCP pairing is growing, and we recommend MCP server developers to start thinking about writing skills that complement their MCP server. Today, we’re releasing two features around skills to help you test skills + MCP pairing.
In MCPJam, you can now view your skills beautifully in the skills tab. MCPJam lets you upload skills directly, which are then saved to your local skills directory.
You can also test skills paired with your MCP server in MCPJam’s LLM playground. We’ve created a tool that contextually fetches your skills so they get loaded into the chat. If you want more control, you can also deterministically inject them with a “/” slash command.
Skills + MCP are a fairly new concept. I would love to hear your thoughts on it!
