What's new

Threadnote 4.6.6 lets agents opt in to PNG pages for large MCP read_context results instead of paged text.

Optional MCP image projection

read_context stays paged text by default. threadnote image-projection --enable returns a complete memory as PNG pages plus a verbatim ID appendix when the text would have paged. Agents can see that memory in one result instead of extra text pages, and a denser visual layout can fit more of the note. Imaging is still lossy for hex and IDs, so trust the verbatim appendix over PNG glyphs. threadnote read on the CLI stays text. Restart connected MCP clients after changing the setting. THREADNOTE_IMAGE_PROJECTION=0 disables imaging without removing the persisted setting.

Host-selected image render profile

The image render profile is selected from the LLM/MCP host via THREADNOTE_MCP_CLIENT (set by mcp-install): Claude Code uses dense Claude pages (claude-sonnet-4-6); Codex uses gpt-5.6-sol; Cursor uses grok-4.5; Copilot and unknown hosts use an 84-column 14px strip. Override with THREADNOTE_IMAGE_PROJECTION_MODEL. MCP does not see the live in-chat model.
