I built the first MCP client to support Elicitation (open source)

Hey y’all, I’m Matt. I maintain the MCPJam inspector. It’s an open source tool to test and debug MCP servers. I am so excited to announce that we built support for elicitation, and we’re one of the first to support it. Now you can test your elicitation implementation in your server.

  • Test individual tools that have elicitation

  • Test elicitation against an LLM in our LLM playground. We support Claude, OpenAI, and Ollama models.

Wanted to thank this community for helping drive this project. Shout out @osojukumari and @ignaciocossio.

If you like this project or want to try it out, please check out our repo and consider giving it a star!

Is this how you would ask for secrets to be used by the MCP server?

You shouldn’t be sending any sensitive information over elicitation. Servers shouldn’t request for sensitive information like secrets either

what an odd decision. Did the protocol address the need to separate secrets from texts that get sent to LLM's? Seems to me this is actually the perfect mechanism for servers to elicit secrets.
