Overview

AI-generated overview

A remote MCP server that checks whether an A2A Agent Card endpoint is reachable and ready for authorized targets.

What you can do
This server exposes a health-check capability for A2A (Agent-to-Agent) Agent Cards. Based on its description, it verifies connection readiness for targets the caller is authorized to check. It is a free, no-storage service, so it does not persist the results it returns. No individual tools are listed in the manifest.
When to use it
Useful when an assistant needs to confirm that an A2A agent endpoint is reachable and responding before relying on it. It fits agent-to-agent integration or debugging workflows where a quick readiness check is wanted.
Requirements
A remote streamable HTTP endpoint; no package installation is needed. The manifest declares no authentication, environment variables, or headers, and no accounts or API keys are shown. Network access to the remote endpoint is required.
Before you install
The description states checks are limited to authorized targets, so only check endpoints you are permitted to probe. The service is described as no-storage, but requests still go to a third-party remote endpoint, so avoid sending sensitive target details. No credentials are requested by the manifest.

Installation

In SourceWeft

  1. Open Agent Card Health Check in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.kadopi%2Fagent-card-health-check/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
