list_catalogs List every A2UI catalog with a when-to-use, so you can pick the extension catalogs a surface needs. The base catalog (a2ui-atoms-v1) is always resolved.
get_catalog Return one catalog's atoms (type + one-line description) so you know its vocabulary.
find_atoms Semantic search over the atom catalog: describe the UI piece you need in plain words and get the best-matching atoms, ranked best-first, each with a description
get_atom_schema Return the PROP SHAPE (field names + what each field takes) for named atoms. get_catalog tells you an atom EXISTS; this tells you how to fill it. Call this befo
required_catalogs Given an A2UI payload, return the resolvable catalog URIs it needs (deterministic — pure function of the atoms).
build_multi_page_surface Build a multi-section A2UI app from raw title+content sections — you never estimate size or decide how to split; each section becomes its own independently-enco
make_surface_url Render an A2UI payload in the CALLER'S OWN environment. Pass renderer_url (your deployed renderer /exec) and get a live URL + the catalogs it declares. Omit ren
preview_url Quick DEMO render on the public renderer (ephemeral, nothing stored). Limited to 2 runs per client, then deploy your own renderer and use make_surface_url. Onbo
render_surface Render an A2UI payload INSIDE the chat as a live interactive view (MCP Apps hosts only — on other hosts this returns the payload as text). No URL, no size ceili
make_film Make a short motion film (a social clip, launch teaser, quote card...) built by the A2UI Design Studio: you choose a template and supply the words; the studio b
sketch_agent_start Start a real, live agent_sketchpad drawing: one Gemini call plans a complete picture as an ordered list of SVG strokes, the first stroke renders immediately, an
sketch_agent_poll Continue a sketch_agent_start task: returns every stroke newer than the given cursor (an event log, not a snapshot — nothing is skipped regardless of poll timin
render_ping Diagnostic: render a tiny test view in-chat (MCP Apps hosts only). Proves view mounting works independent of the full catalog renderer. Echoes back whatever pay
wasm_spike Diagnostic (MCP Apps hosts only): mounts a view that instantiates a tiny hand-assembled WebAssembly module, computes per-frame state in it, renders to canvas, a
diagram_studio Draw a diagram in-chat with the full Diagram Studio interface (MCP Apps hosts only; it opens fullscreen where the host allows it). YOU write the diagram; nothin
amiga Open a real, cycle-exact Amiga 500 emulator in-chat (MCP Apps hosts only). Boots straight into AROS, a free open-source environment (no copyrighted Kickstart RO
distill_document Compile a training.md / roadmap markdown document into a live interactive A2UI app — DETERMINISTIC parser, no model involved. Fact sheet: input is MARKDOWN foll
publish_url STORES the payload server-side and returns a SHORT shareable link. Opt-in only: requires acknowledge_storage=true — confirm with the user first that they accept
unpublish_url Delete a published short link before its TTL using the delete_token returned by publish_url.
emit_deployment 🎓 GRADUATE a tested surface into a dedicated, DEPLOYER-ONLY standing app in YOUR OWN Google Apps Script account. Returns a deterministic recipe (config files +
emit_training_runbook Build a multi-lesson training/course surface as ONE properly-linked page with real in-app tab navigation between lessons — prefer this over build_multi_page_sur
emit_runbook_surface Stamp your content through a DECLARED runbook — a pre-authored, judgment-free surface composition. You supply content only; the runbook supplies the composition
describe_playbook Explain a playbook to a HUMAN as a rendered surface: the frame it reads against, the lenses available, and the questions it will ask them. Compiled from the run
open_workspace Open the A2UI Workspace — a rendered surface that IS the demo: each tool is introduced by the scenario it answers, then wired to run, then shows what it saved.
get_profile Read the signed-in reader's saved profile and recent history. Call this BEFORE asking a runbook's `elicit` questions: if a domain or default lens is already sav
save_profile Update the signed-in reader's profile. Only the keys you pass change; pass null to clear one. Save what the reader TOLD you, never what you inferred from one ar
save_reading Record a stamped surface in the reader's history so it can be compared and reopened later. Call it AFTER emit_runbook_surface, and PASS ITS `payload` — that sto
export_reading Export a kept reading as something that outlives this connector. format "html" returns ONE self-contained file — styles inlined, no network, opens in any browse
render_reading_to_slack Post a kept reading into Slack as real, native Block Kit — the continuity proof: generate here, save it, and the SAME content reopens in Slack, not a link back
list_readings The reader's recent stamped surfaces, newest first — what makes "compare this to my last three teardowns" answerable at all. Optionally filter to one runbook. R
