Install Jentic One Beta

Connect the Magic: The Gathering API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Magic: The Gathering API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fmagicthegathering.io%2Fmagicthegathering" | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fmagicthegathering.io%2Fmagicthegathering" | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

What an agent can do with Magic: The Gathering API.

Use Cases

Patterns agents use Magic: The Gathering API for, with concrete tasks.

★ Card Lookup and Search

An AI agent connected through Jentic can answer questions about specific cards. It searches by name, type, colour, or set and returns matching cards with their attributes, so an assistant can help a player find a card or check its details without a local database.

Search for all cards named Black Lotus and return their set and type

Set and Booster Generation

Tools that simulate opening product need real set contents. The Magic: The Gathering API lists sets and generates a booster pack for a chosen set, letting an agent build a draft pool or simulate a pack opening from authentic set data.

Generate a booster pack for a given set code and return the cards it contains

Game Reference Data

Rules and deck-building assistants need the game's vocabulary. The API lists card types, subtypes, supertypes, and supported formats, so an agent can validate a deck against a format or explain the type line of a card from authoritative data.

List the supported formats and the card types the game defines

Key Endpoints

Why Jentic?

What agents get from Jentic-routed access to this vendor.

Setup

Using the Magic: The Gathering API by hand means constructing search queries, paging through results, and parsing card and set payloads yourself. Through Jentic you install once, import it from the API Directory, and your agent calls the card, set, and format operations directly.

Permission scoping

Every operation is a read that returns game data, so your agent can never modify anything, and you choose which operations it may call. You might allow card and set lookups while blocking booster generation.

Credential isolation

The Magic: The Gathering API is public and needs no API key, so there is no credential to store or inject. Your agent calls the endpoints directly through your own Jentic One instance.

Intent-based discovery

Agents search Jentic by intent such as 'search cards by name', and Jentic returns the matching operation with its input schema so the agent calls it with the right filters.

FAQs

Specific to using Magic: The Gathering API through Jentic.

Does the Magic: The Gathering API require authentication?

No. The Magic: The Gathering API is free and public and requires no API key or credential. Every endpoint is a read that returns card and game data, so an agent can call it without any sign-up. Through Jentic you import it and your agent calls the operations directly.

Can I limit what my agent is allowed to do with the Magic: The Gathering API?

Yes. Every operation is a read that returns game data, so the agent can never change anything, and you choose which operations it may call. You might allow card and set lookups while blocking booster generation, with every call logged by your own instance.

Is there a Magic: The Gathering MCP server?

You don't need an MCP server to give your agent the Magic: The Gathering API. Jentic connects it directly from the API Directory: import it and your agent calls the card, set, and format operations. Operations are discovered on demand, so nothing extra loads into the agent's context.

What are the rate limits for the Magic: The Gathering API?

According to its documentation the API is rate limited to 5000 requests per hour per IP address. It requires no key, so plan your agent's calls against that hourly ceiling before running high-volume searches.

What data does the Magic: The Gathering API cover?

It covers cards, sets, and game vocabulary. You can search cards by attributes, retrieve a card or set by identifier, generate a booster pack for a set, and list card types, subtypes, supertypes, and supported formats.

How do I search for a card through Jentic?

Search Jentic by intent, for example 'search cards by name', and Jentic returns the matching Magic: The Gathering operation with its input schema. Your agent supplies the search filters and reads back the matching cards. To run it on your own infrastructure, install Jentic One from its GitHub repo.
