Pick the AI app you use, then copy the settings.

Passed 3/3 checks · Runs on your computer · ✓ Commands checked Nov 14, 2026

First: which AI do you use?

Pick your app and the steps appear below.

Works with Claude, with some setup first

Install Python (uv) on your computer first (one time) · Only the Claude desktop app (Windows or Mac), not the web or phone

Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server Agent Card Starter for Claude on this computer, in this order: 1) Check uv with uv --version. If it is missing, tell me to install it from https://docs.astral.sh/uv/getting-started/installation/; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "agent-card-starter": { "command": "uvx", "args": [ "agent-card-starter" ] } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) No key is needed. 5) Do what we agreed, then check that the Agent Card Starter tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

  1. Install uv (if you don’t have it)

    Already installed? Check first · Open Terminal, type this command and press Enter

    uv --version
    • A version number such as uv … = installed, skip this step
    • "command not found" (on Windows: "is not recognized") = not installed yet, or installed but Terminal needs to be closed and reopened
    How to open Terminal

    Mac: press ⌘ + Space, type Terminal, press Enter

    Windows: open Start, type Windows PowerShell, then Open

    Not installed: uv has no click-through installer. Copy the one-line command for your system (macOS or Windows) from uv’s official page into Terminal · no separate Python install needed; uv downloads it when required

    Open the uv download page ↗

    When it’s done, close Terminal, open it again and run the same command. You should see a version number: uv --version

    Install once; it works for everything that needs uv

  2. Open the Claude desktop app’s settings file

    SettingsDeveloperEdit Config

  3. Paste these settings and save the file

    {
      "mcpServers": {
        "agent-card-starter": {

          ]
        }
      }
    }
  4. Quit Claude and open it again

  5. Try it

    Use Agent Card Starter and tell me what you can do for me, then show me one thing

    ✓ If Claude says it is using Agent Card Starter or shows a Agent Card Starter tool in the answer, you are connected

Common questions

Is Agent Card Starter safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 9 days ago, and the latest version (0.2.2) reached the registry 16 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

agent-card-starter

Write and check the machine-readable card that makes a small business readable for AI assistants. Its WordPress sibling, Open Door for AI Assistants, goes one step further: an AI assistant will be able to leave an inquiry for the business, and the business gets it as an e-mail (inquiry service coming soon).

In 60 seconds: AI assistants read a small JSON file to learn what your business does. This tool writes that file for you and checks it. Offline, no account, no dependencies.

pip install agent-card-starter

agent-card init --name "Muster Roofing Ltd" --description "Roofer in Musterstadt, repairs and new roofs." --website https://www.example.com --skill "Flat roof sealing" agent-card validate .well-known/agent-card.json --strict

Upload the file to https:// /.well-known/agent-card.json and you are readable. Nothing here guarantees that an assistant will mention you.

In 60 Sekunden: KI-Assistenten lesen eine kleine Datei, um zu erfahren, was Ihr Betrieb macht. Dieses Werkzeug schreibt die Datei und prüft sie. Ohne Netz, ohne Konto, ohne Fremdpakete. Befehle siehe oben, die Datei kommt nach https:// /.well-known/agent-card.json.

Starter kit to make a small business readable and reachable for AI assistants: an A2A agent card, an MCP server card, a minimal MCP example server and a validator. Standard library only, Python 3.9+, MIT licensed.

Starter-Set, damit ein kleiner Betrieb für KI-Assistenten lesbar und erreichbar wird: Agentenkarte (A2A), Server-Karte (MCP), ein minimaler MCP-Beispielserver und ein Prüfskript. Nur Python-Standardbibliothek, ab Python 3.9, MIT-Lizenz.

Maintained by flowboxx, an agency that builds AI doors for businesses. Gepflegt von flowboxx, einer Agentur, die KI-Türen für Betriebe baut.

Use it for your business
  1. Copy examples/well-known/agent-card.json, replace name, description, provider, skills.
  2. List only services you really offer. One skill per service, stable ids.
  3. Keep prices, phone numbers and promises out of the card. A human answers those.
  4. Run the validator, publish the file at https:// /.well-known/agent-card.json.
  5. Point supportedInterfaces at an endpoint you really operate. The example server speaks MCP over stdio for learning. A public endpoint needs HTTP transport, rate limiting, spam protection and a privacy notice. anfrage_anlegen is a stub on purpose.
Notes on the standards
  • The agent card follows the A2A v1.0 field names (supportedInterfaces, skills, provider).
  • The server card follows the MCP Server Card proposal (SEP-2127). It is an extension and the schema may still change. Check the current schema before you publish.
  • The validator checks required fields and a few sanity rules. It is not a full JSON Schema validation.
  • Nothing here guarantees that an assistant will mention or recommend you.

  1. examples/well-known/agent-card.json kopieren, Name, Beschreibung, Anbieter und Fähigkeiten ersetzen.
  2. Nur Leistungen eintragen, die Sie wirklich anbieten. Eine Fähigkeit je Leistung, stabile Ids.
  3. Keine Preise, Telefonnummern oder Zusagen in die Karte. Das beantwortet ein Mensch.
  4. Prüfskript laufen lassen, Datei unter https:// /.well-known/agent-card.json ablegen.
  5. supportedInterfaces auf einen Endpunkt zeigen lassen, den Sie wirklich betreiben. Der Beispielserver spricht MCP über stdio zum Lernen. Ein öffentlicher Endpunkt braucht HTTP, Mengenbegrenzung, Spam-Schutz und einen Datenschutzhinweis. anfrage_anlegen ist absichtlich ein Stub und speichert nichts.
Hinweise zu den Standards
  • Die Agentenkarte folgt den Feldnamen von A2A v1.0 (supportedInterfaces, skills, provider).
  • Die Server-Karte folgt dem MCP-Vorschlag Server Card (SEP-2127). Das ist eine Erweiterung, das Schema kann sich noch ändern. Vor dem Veröffentlichen das aktuelle Schema prüfen.
  • Das Prüfskript prüft Pflichtfelder und einige Plausibilitäten, keine vollständige JSON-Schema-Validierung.
  • Nichts hier garantiert, dass ein Assistent Sie nennt oder empfiehlt.
