FAQs on using Merge's Sanity MCP server

What is a Sanity MCP?

It's an MCP server that connects your agents to Sanity's headless CMS through tools. Your agents can invoke these tools to query documents with GROQ, create and update content, manage datasets, register webhooks, and review document history, and more.

Sanity offers an official MCP server, but you can also use one from a third-party platform, like Merge Agent Handler.

How can I use the Sanity MCP server?

The use cases naturally depend on the agent you've built, but here are a few common ones:

Content retrieval for AI-powered responses: When a support bot receives a question, an agent queries Sanity documents using GROQ to find the most relevant knowledge base article and returns the content directly in the response, without requiring a separate search service or manual content lookup

Automated content creation from external events: When a product changelog entry is merged in GitHub, an agent creates a corresponding Sanity document with the release title, description, and date, keeping the website's changelog section current without any manual CMS editing

Webhook provisioning for new projects: When a new Sanity project is spun up, an agent registers the necessary webhooks pointing to the correct downstream endpoints, automating setup that would otherwise require a developer to configure manually in the Sanity dashboard

Content audit for compliance reviews: When a compliance review is triggered, an agent retrieves the document history for a set of Sanity content items, compiling a record of what changed and when, and posts the audit summary to a designated Slack channel for review

What are popular tools for Sanity's MCP server?

Here are some of the most commonly used tools:

query_documents: executes a GROQ query against a Sanity dataset and returns matching documents. Useful for agents that need to search or filter content before deciding what to retrieve, create, or surface in a response

get_document: retrieves a specific Sanity document by ID, including all fields and their current values. Call this when an agent needs the full content of a known document before displaying, summarizing, or updating it

create_document: adds a new document to a Sanity dataset with the specified type and field values. Good for workflows that need to land content in the CMS automatically when triggered by an external event

patch_document: applies targeted field-level updates to an existing Sanity document without overwriting the full record. Use this when an agent needs to update a specific field, such as a publication status or revised body copy, while leaving other content intact

create_webhook: registers a webhook on a Sanity dataset so that an external system receives notifications when documents change. Helpful when an agent handles project setup and needs Sanity to push content events to a downstream system rather than polling for updates

get_document_history: returns the revision history for a specific document, including timestamps and field-level changes. Call this when an agent needs to audit content changes or identify when a specific edit was made

What makes Merge Agent Handler's Sanity MCP server better than alternative Sanity MCP servers?

Here is why Merge Agent Handler is worth considering alongside or instead of the official Sanity MCP server:

Enterprise-grade security and DLP: Merge Agent Handler includes built-in data loss prevention controls that let you block or redact sensitive fields before they reach an agent. For Sanity, this means you can prevent draft content, unpublished posts, or internal documentation from being surfaced to agents that should only see published material

Managed authentication and credentials: Merge stores and refreshes your Sanity tokens on your behalf. You never pass raw credentials to an agent or manage token rotation as projects and datasets change

Real-time observability and audit trail: Every Sanity tool call is logged with the timestamp, tool name, input parameters, and response. You can see exactly which documents an agent queried, created, or modified across any dataset without adding instrumentation to your content pipeline

Tool Packs and controlled access: Tool Packs let you define exactly which Sanity tools each agent can reach. A content retrieval agent gets query_documents and get_document. It never gets access to delete_document, delete_dataset, or other write tools it has no reason to use

How can I start using Merge Agent Handler's Sanity MCP server?

You can take the following steps:

1. Create or log into your Merge Agent Handler account.

2. Install the Merge CLI by running pipx install merge-api, then run merge configure to link the CLI to your Merge account and merge login to authenticate your session.

3. Register the Agent Handler MCP server with Claude Code by running claude mcp add --transport http agent-handler https://ah-api.merge.dev/mcp, then open Claude Code and run /mcp to confirm agent-handler appears with a connected status.

4. Select agent-handler from the MCP list. This opens a browser window where you select which integrations to authenticate. Choose Sanity and complete the OAuth flow. Merge stores and manages the credentials going forward.

5. Open a Claude Code session and start querying Sanity data directly. The first time you use a Sanity tool, a Magic Link may appear to complete connector authentication.

If you want to connect Merge Agent Handler's Sanity MCP with internal or customer-facing agentic products, you can follow the steps in our docs.
