- !Follows MCP best practices (not scored yet)note
2 tips (not scored)
- !Very common tool names: search, fetch. Next to other servers' tools the AI may mix them up; a short prefix helps (like "github_search" instead of "search").
- !10 tools don't say whether they reach outside services like the web (openWorldHint): search, fetch, search_assets, get_asset, get_agent_commerce_manifest, get_asset_manifest and 4 more
