Design and enforce Agent-to-UI communication protocols. Use when: design agent ui protocol, implement a2ui, build genui.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# a2ui-protocols ## Goal Design, enforce, and integrate robust Agent-to-UI (A2UI) communication protocols using Generative UI and HTMX conventions. ## Steps 1. **Analyze Requirements**: Understand the data exchanged between the agent and the frontend UI. 2. **Design Protocol**: Define the JSON schema, WebSocket events, or Server-Sent Events (SSE) required for the agent to stream UI components. 3. **Implement A2UI**: Configure the backend to serve dynamic UI chunks (e.g., using React Server Components, HTMX responses). 4. **Verify**: Ensure the UI updates smoothly without full page reloads and maintains state. ## Security & Guardrails ### 1. Skill Security - **Injection Prevention**: Validate all incoming data from the UI to prevent command/SQL injection on the agent backend. - **Resource Constraints**: Limit WebSocket connections and payload sizes to prevent DoS via flood requests. ### 2. System Integration Security - **Origin Verification**: Explicitly enforce strict CORS policies for all A2UI REST/WebSocket endpoints. - **State Integrity**: Prevent client-side manipulation of agent context IDs or session tokens. ### 3. LLM & Agent Guardrails …

How to install
mdr add andreibesleaga/gabbe/a2ui-protocols@sha256:dfc919943c25856dThe line at the top of this page pins the label git:20261014.de0823c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
