Following up on this PR (12+ hours since submission, awaiting maintainer review).

Quick status note for reviewers: The PR currently uses:

• mcp.buywhere.io (deprecated, NXDOMAIN)
• io.github.BuyWhere/buywhere-api namespace
• Version 0.1.0

The canonical configuration (live today) is:

• https://api.buywhere.ai/mcp (canonical endpoint)
• io.github.BuyWhere/buywhere-mcp (matching npm package @buywhere/mcp-server)
• Latest version 1.0.4 (with the auth header fix from BuyWhere/buywhere-mcp#4603226)

Recommended path forward (faster than re-reviewing this PR):

• Close this PR as superseded
• Open a new PR with the corrected server config (api.buywhere.ai/mcp endpoint, buywhere-mcp namespace, v1.0.4)
• Reference BuyWhere/buywhere-mcp issue #18 for the auth fix context

If maintainers prefer the iterative-update path (commits on this PR), I'm happy to do that too. Just let me know which approach is faster.

Reference data: https://registry.modelcontextprotocol.io/v0/servers?search=buywhere (current v1.0.4 row)

Update (2026-06-12): Pushed a fix to shorten the description (was 163 chars, now <100).

Also opened a complementary PR #1357 with the correct namespace io.github.BuyWhere/buywhere-mcp (matching the canonical npm package @buywhere/mcp-server) and the latest version 1.0.4 (with the auth header fix from BUY-42672).

Recommendation for maintainer: Close this PR (#1356) and merge #1357 instead. The #1357 entry:

• Uses the correct namespace (buywhere-mcp not buywhere-api)
• Uses the correct endpoint (https://api.buywhere.ai/mcp not mcp.buywhere.io)
• Uses the latest version 1.0.4 (not 0.1.0)
• Has a description that passes the 100-char schema validation

/tmp/mcp-publisher validate passes on the new file. The BuyWhere/registry fork is in sync with the modelcontextprotocol/registry for both branches.
