Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

compile

compile_handoff

Compile source-agent outputs into a receiver-ready handoff package. The receiving agent declares required output identifiers, accepted media types, filenames, and constraints. The tool maps source outputs to that contract, rejects missing or ambiguous inputs, and returns a portable package only when required outputs are satisfied.

inspect

inspect_handoff

Inspect a handoff package and return an acceptance decision. The tool recalculates deliverable hashes, checks expiry and contract satisfaction, and returns the receiving agent's next action.

prepare

prepare_artifact

Prepare content for transfer to another agent or a human reviewer. `target_modes` accepts either a JSON list or an actual list of MIME types. The result includes expiring artifact URLs, SHA-256 hashes, a manifest, and a downloadable ZIP package.

How do I connect A2A Artifact Handoff?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does A2A Artifact Handoff need an API key?

No. A2A Artifact Handoff completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
