mcp-slim
Allows inspection and evaluation of Puppeteer MCP servers, providing scorecards and recommended improvements.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mcp-slimanalyze the demo OpenAPI spec"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
mcp-doctor ? Agent Readiness Platform (MCP wedge)
The easiest way to score MCP agent readiness.
Open-source CLI — inspect, benchmark, and eval MCP servers before agents hit production.
"We prove agents can actually use your MCP."
