Using Magisterium AI with other MCP / A2A clients

Besides ChatGPT and Claude, Magisterium AI works with any client that speaks the Model Context Protocol (MCP) or our agent-to-agent (A2A) endpoint.

Supported clients (examples)

Cursor, VS Code Copilot, and other IDEs with MCP support.
n8n, Zapier, and similar automation platforms via their MCP integrations.
Custom agents built on frameworks like LangChain, LlamaIndex, or your own.
Cloud agent platforms with A2A support.

The specific setup varies by client, but the pattern is the same: point the client at our MCP or A2A endpoint and authenticate with your Magisterium AI API key.

Configuration

MCP endpoint URL — see magisterium.com/developers/docs/mcp.
API key — create one at magisterium.com/developers/api.

Paste both into your client's MCP config.

The /developers page titled 'Developers' with the lead 'Leverage the knowledge of Magisterium AI in your own application! We offer various services to help you build with Magisterium AI and leverage its knowledgebase.' An 'Our Services' grid shows four cards: Chat API, Search API, MCP ('Bring Magisterium AI to your AI tools'), and A2A ('Connect AI agents to Magisterium AI'). Below it, a 'Get Started' section has API Key (Login button) and MCP Server (with a copy-pill showing 'MCP.MAGISTERIUM.COM'), plus 'Try the API' and 'Explore docs' shortcuts. — Developers page (MCP integration section)

Common tools exposed

Once connected, your client can use tools such as:

Search the Magisterium AI library (retrieve relevant magisterial or theological passages).
Query documents for passage-level citations.
Scripture lookups across Catholic translations.

Tool names and schemas are documented on the Developers page.

A2A

For agent-to-agent workflows that don't support MCP natively, we offer an A2A endpoint. The documentation on magisterium.com/developers covers the setup.

Plan-based limits

MCP and A2A both require a paid plan. Free accounts get a PLAN_REQUIRED error.

Pro / Organization: Unlimited requests per day, 15 / minute combined MCP + A2A.
Enterprise / Large Organization: Custom — contact us.
The Q&A pipeline (chat / catholic_qa) is capped at 2 / minute on paid plans.

Rate-limit response headers tell your client what's available.

Help with a specific client

If you're setting up a new or unusual client and something isn't working, contact us and choose API. Include your client name, the error you're seeing, and any logs.
