Summary

Updates the "MCP SDKs" reference in docs/host-integration.md to the current MCP SDK documentation URL.

Why

Fixes #3589. The linked page https://modelcontextprotocol.io/sdk/java/mcp-overview returns 404 after the modelcontextprotocol.io docs restructure. The SDK overview is now served at https://modelcontextprotocol.io/docs/sdk (verified 200, "SDKs" page).

What changed

• docs/host-integration.md: one entry under "Additional Resources" now points at https://modelcontextprotocol.io/docs/sdk.

MCP impact

• No tool or API changes

Documentation only.

Prompts tested (tool changes only)

• N/A — no tool changes.

Security / limits

• No security or limits impact

Tool renaming

• I am not renaming tools as part of this PR

Lint & tests

• Linted locally with ./script/lint
• Tested locally with ./script/test

Neither script was run: this machine has no Go toolchain, so the scripts cannot build the server. The change is a single URL inside a Markdown file; git diff --check is clean, the diff is one line, and the old/new URL status was checked with curl (404 → 200).

Docs

• Updated (README / docs / examples)

This change was prepared with AI assistance and reviewed before submission.

Verified the new target: https://modelcontextprotocol.io/docs/sdk returns 200 (301 to /docs/2026-07-28/sdk, the versioned canonical page), while the old https://modelcontextprotocol.io/sdk/java/mcp-overview is a hard 404. Keeping the unversioned /docs/sdk rather than the versioned target is the right choice here - the alias follows the current spec release, so the link will not rot when the next version ships. The rest of the Additional Resources list checks out. No objection.

Closing this as superseded: #3598 already fixed the same line (the MCP SDKs link in docs/host-integration.md) and was merged into main. The change here is now empty after the base was updated, so there is nothing left to land. Thanks!
