A2areplayreceipt MCP

What a2areplayreceipt-mcp MCP server does

The a2areplayreceipt-mcp MCP server provides a remote interface for examining and documenting failures in A2A workflows. It is aimed at teams that need a repeatable way to replay an agent failure, determine the likely error category, consider a retry approach, and preserve the result as reviewable evidence.

The service is hosted at https://a2areplayreceipt.clauxel.com/mcp. Clients connect through MCP rather than running repository source locally. The repository is a public documentation project; it does not include the production implementation, credentials, payment settings, infrastructure configuration, customer records, or private analytics.

How it works

An MCP-compatible client sends tool calls to the hosted Streamable HTTP endpoint. The available workflow can begin with replaying an A2A failure, followed by error classification and retry-plan generation. A replay receipt can then record the outcome, while the failure-log export supports sharing or reviewing the resulting evidence.

The service also publishes a server card at https://a2areplayreceipt.clauxel.com/server-card.json. Its registry identifier is com.clauxel.a2areplayreceipt/a2areplayreceipt-mcp. Production calls use bearer-token access, although the supplied material does not specify token acquisition, request headers, account provisioning, or client configuration syntax.

Setup and configuration

Use an MCP client that can connect to a remote Streamable HTTP server and point it at:

https://a2areplayreceipt.clauxel.com/mcp

The a2areplayreceipt-mcp MCP server is hosted, so the repository itself is not something to build or launch as a local implementation. The documentation identifies bearer tokens as the access method for production calls, but it does not list an environment variable name or provide a complete authentication setup. Consult the project’s hosted documentation or support channel for access and account details.

Tools and capabilities

The published tool set includes:

• replay_a2a_failure for replaying an A2A failure scenario.
• classify_agent_error for categorizing an agent error.
• suggest_retry_plan for producing a proposed retry approach.
• issue_replay_receipt for creating a structured replay receipt.
• export_failure_log for exporting failure-log evidence.

The stated capabilities also include structured tool-call output, receipt-oriented evidence export, a public server card, and registry metadata. These features suit workflows where a failure needs more than an informal explanation and should be presented to a reviewer or retained as an audit-oriented record.

Limitations and notes

The a2areplayreceipt-mcp MCP server is documented as a remote service, not as an open-source local server in this repository. The supplied material does not describe the input schema for each tool, the exact receipt format, retention behavior, supported authentication lifecycle, pricing requirements, rate limits, or the A2A systems that can be replayed.

The documentation names developer platform teams, release owners, AI engineering leads, and delivery reviewers as its intended audience. Treat the public repository as reference material for the hosted service rather than evidence that production code or sensitive operational data is available locally.
