What is the Hygraph (Headless CMS) MCP Server?
Connect your Hygraph project to any AI agent and take full control of your federated content and headless CMS architecture through natural conversation.
What you can do
- GraphQL Orchestration — Execute complex nested queries and mutations directly from your agent to fetch or update structured content without manual REST endpoints
- Schema Introspection — Discover content models and list available fields to understand your project's data structure and scalar parameters automatically
- Document Lifecycle — Create, update, and publish CMS documents, moving content from Draft to Published stages with precise ID targeting
- Media Management — Enumerate media assets and retrieve secure handles and cloud URLs required for frontend delivery and display
- Localization Audit — List project locales and translation spaces to identify which content stages are mapped to specific internationalization rules
- Cleanup Operations — Irreversibly delete specific content nodes and documents to maintain a clean and optimized content repository
How it works
1. Subscribe to this server
2. Enter your Hygraph API Endpoint and Auth Token
3. Start managing your content architecture from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Frontend Developers — test GraphQL queries and introspect content models without leaving your IDE or opening the Hygraph Playground
- Content Architects — audit schema definitions and verify field configurations across multiple content models through natural conversation
- Digital Editors — create and publish draft content quickly by commanding your AI agent to update specific document fields
Built-in capabilities (10)

Frequently asked questions
Can I test complex GraphQL queries through my agent?
Yes. Use the execute_graphql_query tool to run any valid GraphQL query block. Your agent will return the nested document results, making it an ideal way to verify content fetching without using the Hygraph Playground.
How do I publish a draft document using my agent?
The publish_cms_document tool allows your agent to shift a document's stage from DRAFT to PUBLISHED. You just need to provide the Model Name and the Target UUID to make the content live on your frontend.
Can I see all available fields for a specific content model?
Absolutely. Use the get_model_fields tool with the name of your Model (e.g., 'Post' or 'Product'). Your agent will perform a schema introspection and list all fields, types, and scalar parameters defined in that model.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Hygraph (Headless CMS) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
