Before you upgrade#
- Check the changelog for changes since your installed version.
- Check the runtime requirements and migration notes.
- Test your client configuration and documentation queries with the new version.
For the MCP server, version 2 replaced get-library-docs with query-docs and
introduced query-based retrieval. Version 3 introduced HTTP sessions; version 4
removed those sessions and uses stateless HTTP serving. See
Architecture & Operational Behavior for current
transport behavior.
Tool descriptions ask agents to use each tool at most 3 times per question. This instruction does not create a server-enforced request limit. See rate limits for account and request limits.
