Where does one find the tool prompts that explains to the LLM how to use those seven tools and what each does? I couldn’t find it easily looking through the rep

You can see it in the cline repo which does prompt based tooling, with Claude and several other models.

You can find these here: https://github.com/search?q=repo%3Aaperoc%2Ftoolkami%20%40mcp.tool()&type=code https://github.com/search?q=repo%3Aaperoc%2Ftoolkami%20%40mc...

  mplewis thanks for helping to point those out!

    I find it very interesting that the LLM is told so little details but seems to just intuitively understand based on the english words used for the tool name and function arguments. I know from earlier discussions that this is partially because many LLMs have been fine tuned on function calling, however the model providers don’t share this training dataset unfortunately. I think models that haven’t been fine tuned can still do function calling with careful instructions in their system prompt but are much worse at it. Thank you for comments that help with learning and understanding MCP and tools better.

  Thank you. I find in interesting that the LLM just understands intuitively from the english name of the tool/function and it’s argument names. I had imagined it might need more extensive description and specification in its system prompt, but apparently not.

Related. Here is info on how custom tools added via MCP are defined, you can even add fake tools and trick Claude to call them, even though they don't exist. This shows how tool metadata is added to system prompt here: https://embracethered.com/blog/posts/2025/model-context-protocol-security-risks-and-exploits/ https://embracethered.com/blog/posts/2025/model-context-prot...
