Hygraph MCP server

What the model can do

Hygraph headless CMS: the project's content models (found by introspection), entries of any model with previews of their text fields and their created, updated and published dates, and assets with file names, types and sizes. When asked, creates, updates, publishes, unpublishes or deletes one entry, and creates from a URL, publishes, unpublishes or deletes one asset.

Reads

• hygraph_list_modelsThe content models in the Hygraph project (Post, Product, Author…), each with the query name used to list its entries and the text fields previewed.
• hygraph_list_entriesEntries of one Hygraph model, newest change first by default: id, created, updated and published dates, and short previews of the model's text…
• hygraph_list_assetsAssets (images, documents, video) in the Hygraph project, newest change first: file name, MIME type, size in bytes, dimensions for images…

Acts, when you ask

These change something in Hygraph. The model is told to use them only when you ask for exactly that, and each one is granted by name: per team on a shared connection, by the owner on a personal one.

• hygraph_create_entryCreate one entry in a Hygraph model, as a DRAFT (nothing is published until hygraph_publish_entry).
• hygraph_update_entryChange fields of one Hygraph entry by id.
• hygraph_publish_entryPublish one Hygraph entry's draft to a content stage (normally PUBLISHED), making it live for everyone who reads that stage, such as the website.
• hygraph_unpublish_entryUnpublish one Hygraph entry from a content stage (normally PUBLISHED): readers of that stage, such as the website, no longer see it.
• hygraph_delete_entryPermanently delete one Hygraph entry by id, from every stage.
• hygraph_create_asset_from_urlCreate a Hygraph asset by having Hygraph fetch a file from a public https URL, as a DRAFT.
• hygraph_publish_assetPublish one Hygraph asset to a content stage (normally PUBLISHED), so entries on that stage can show it.
• hygraph_unpublish_assetUnpublish one Hygraph asset from a content stage (normally PUBLISHED); readers of that stage lose it.
• hygraph_delete_assetPermanently delete one Hygraph asset by id; entries that use it lose it.

Connect it

First connect Hygraph on Dashboard → Connections, then add Memtro to your client once. The Hygraph tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared Hygraph connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.

Questions

Is this an official Hygraph MCP server?

No. It is Memtro's MCP server with Memtro's Hygraph connector behind it: the connector reads Hygraph through its API with the credentials you connect on Dashboard → Connections, and Hygraph publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

What does it cost?

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in Hygraph?

Only when you ask, and only what it has been granted: create a draft entry in a model; update fields of one entry (the draft, published content changes when it is published); publish one entry to a content stage (readers of that stage see it); unpublish one entry from a content stage (readers lose it); delete one entry (permanent); create an asset from a public URL; publish one asset; unpublish one asset; delete one asset (permanent). Every other tool reads, searches or lists. An administrator grants each acting tool by name per team, and a personal connection acts only after its owner allows it.

Which clients work?

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.
