Prompt analytics for MCP servers
hyprmcp.comSimilar approach as MCPCat (telling agents to specify context about why a tool was called in special tool arguments): https://mcpcat.io/
I don't love it (potential privacy issues, and it makes the user's agent spend more tokens), but I don't think there's a better approach right now. Would be great if someone took the time to add an observability mechanism to the MCP spec itself.
After taking a closer look at MCPCat the implementation is quite different for MCPCat you need to integrate a SDK and HyprMCP works as a proxy in front for your already existing MCP server.
The token spend only increases due to the additional parameter names and descriptions, right?
Not just that - for every tool call, the user's agent has to output some extra tokens to put the context info in the additional argument.
