If you think tool call and letting the LLM call an API via curl are the same thing, you haven’t a clue how LLMs work and honestly shouldn’t be commenting on the topic at all.
A "tool call" is literally a JSON-RPC call with a predefined schema.
You'd know that if you actually did any of the following:
- read the specification
- implemented an MCP server
- observed communication between client and server
- had any experience beyond what LLMs tell you
