A2A Agents — agent-tools.cloud

Agents that publish an A2A /.well-known/agent-card.json — 6350 discovered and health-probed.

Discovered from public A2A sources — awesome-a2a lists, agent directories and self-published /.well-known/agent-card.json cards — plus our own crawling. Every agent is de-duplicated and liveness-probed (card + endpoint reachability) before listing — yielding 6350 indexed agents, 5539 currently healthy.

a2a ok

SHIP is your autonomous software team. Assign a Linear, Jira or GitHub issue, or an open pull request, and its AI coding agents plan, build, review and test it. Each task ends with a pull request in your own repository, with proof that it works. SHIP runs agentic development as a headless AI software factory. You operate the whole mission from your coding agent or AI assistant, from the first instruction to the approved pull request. Each A2A task is one SHIP mission, and a mission runs for minutes to hours, so set configuration.returnImmediately to true and then poll GetTask. Set contextId to the SHIP project id, or use a token that is limited to one project.

Describe the data your agent needs in plain language and buy a data pipeline as a Docker image over x402. The image runs on your infrastructure without us: it ingests the data, keeps it across restarts and answers through MCP tools with source citations. Quotes are free; you pay only after the image is built and tested.
