Dependency Issue?

I'm having trouble starting up the mcp. The mcp dependency was bumped to 0.17.2 but the code wasn't updated to use the new constructor.
```
io.modelcontextprotocol.sdk/mcp {:mvn/version "0.17.2"}
```

There's a constructor mismatch with McpSchema$Tool. HEAD is broken with its own declared 0.17.2 dependency — the clojure-mcp code at core.clj:92 calls constructors that changed between SDK versions.

Start at core.clj:92 and inspect the McpSchema$Tool constructor available in the declared io.modelcontextprotocol.sdk/mcp 0.17.2 dependency. Compare the existing calls with that API, update the constructor usage, and verify that the MCP starts successfully with the declared dependency.
