Tools

• check_identifiers ~211 tokens
  Look up many identifiers at once before shipping code: model ids, API endpoints (/v1/assistants), MCP tool names, SDK methods or field names. For each one, a one line answer and the ids of matching records, plus the records themselves. A record scoped to some code (for example only repos that depend
• check_model ~214 tokens
  Look up one AI model id (for example gpt-4o-2024-05-13 or claude-sonnet-4-5) in apiwatch's reviewed feed of vendor changes before you use it in code. Returns a one line answer (when it stops working, changes behavior, or its deprecation key date) and each matching record with the date, what to do an
• get_record ~138 tokens
  Get one apiwatch record in full, as published: what changes, what to do, the strings to search for, ids it does not cover, where it applies, the vendor source and when it was reviewed. Use an id from another tool's result.
• list_upcoming ~183 tokens
  List the dated changes in apiwatch's feed from today forward, soonest first: model retirements, breaking API changes, silent behavior changes and deprecation key dates. Use it to plan migrations. Optionally limit to the next N days (default 90, max 365) or one vendor. Max 50 records.
• list_watched_mcp_servers ~130 tokens
  List the public MCP servers whose tools apiwatch checks every 6 hours (tools/list only, no login, no tool calls), with each one's status (answering, needs a login, not reachable), tool count, last check and last observed change. Use it to see which servers mcp_server_changes can answer about. Return
• mcp_server_changes ~247 tokens
  Before you rely on a public MCP server's tools, ask whether apiwatch saw them change: tools removed or renamed, new required parameters, rewritten descriptions, changed safety hints. Give a watched server's slug, URL or registry name. Returns a one line answer and the confirmed changes in the last N
• search_changes ~200 tokens
  Search apiwatch's feed of reviewed vendor changes by text: a case-insensitive match on each record's summary, vendor and signatures (the strings to look for in code). Use it when you know a product or feature name but not the exact id. Newest key date first; default 20 results, max 50.
