# a2areplayreceipt-mcp

A hosted MCP server that replays failed A2A agent calls, sorts the error into a type, and hands back a receipt with the failure log.

## What it does

The endpoint is `https://a2areplayreceipt.clauxel.com/mcp`, served over Streamable HTTP. Five tools ship with it: `replay_a2a_failure` reruns a call that broke, `classify_agent_error` labels what went wrong, `suggest_retry_plan` lays out a retry, `issue_replay_receipt` produces the receipt, and `export_failure_log` dumps the log. Tool output is structured, so it drops straight into a review thread.

Production calls need a bearer token. Skip that and the server rejects the request. The repository holds documentation only — no source, no credentials, no payment setup — so self-hosting is not on the table here.

The server card lives at `https://a2areplayreceipt.clauxel.com/server-card.json`, and the registry name is `com.clauxel.a2areplayreceipt/a2areplayreceipt-mcp`. Platform teams, release owners and delivery reviewers are the ones who get mileage out of this.

## When to use it
- reproduce a failed agent call and find the step that broke
- sort agent errors into types instead of reading raw logs
- get a retry plan after a failed run
- produce a replay receipt a reviewer can check
- export the failure log in structured form

## Example prompts
- Replay the failed agent call with `replay_a2a_failure` and show me which step broke
- Classify the error from the last run and suggest a retry plan
- Issue a replay receipt for this failure and export the log
