MCP tool listing may fail due to incomplete pagination

By PulseAugur Editorial · [1 sources] ·

A technical article discusses a potential issue with MCP (Message Communication Protocol) tool listing, where tools registered by a client might not appear. The core problem is ensuring that pagination completes successfully, meaning all pages of tools offered by the server are requested and returned. The article outlines specific rules from MCP specifications regarding cursors and pagination, highlighting differences between versions 2025-06-18 and 2026-07-28. It also notes that tool lists can legitimately change based on server versions or user authorization, and points to a documented issue (Codex issue 28858) where clients failed to retrieve all paginated tools.
