How to integrate Prismic MCP with Atomic Agent

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Prismic.

This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Prismic account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to Prismic

Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.

Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

Connect Prismic to Atomic Agent

1. Sign up or sign in to the Composio dashboard. Copy your API key.
2. In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
3. Ask Atomic Agent to do something in Prismic. It searches Composio for the right tool.
4. On first use, open the sign-in link returned in the chat. Connect your Prismic account, then return to Atomic Agent to continue.

Headless setup

Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

The Prismic MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Prismic account. It provides structured and secure access to your content repository, so your agent can search, retrieve, filter, and organize content, as well as gather repository details—all without manual coding.

• Full-text and predicate-based search: Instantly ask the agent to find documents using keywords, tags, or advanced predicates for highly targeted content discovery.
• Retrieve documents by custom fields or type: Fetch content based on custom fields, document types, or tags, making it easy to surface exactly what you need from your CMS.
• Get and sort documents with advanced ordering: Let your agent return documents ordered by fields like date or title, supporting content workflows where order matters.
• Fetch detailed repository metadata: Have the agent pull repository settings, available refs, types, and supported languages for a comprehensive view of your content environment.
• Access integration fields and enriched content: Retrieve documents including data from integration fields, so your agent can work with richer, more connected content structures.

Use Prismic from Atomic Agent

With your account connected, ask Atomic Agent to work with Prismic in natural language. You can connect more apps through the same Composio integration as you need them.
