Sanity API
Headless CMS with a real-time content lake, GROQ query language, and MCP server, supporting highly customizable content models with live collaboration.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
API tokens with viewer/editor/administrator levels. Dataset-level access control. SOC2 Type II. GROQ query language is powerful but agents must sanitize user-supplied queries to prevent data exposure. Read vs write tokens should be separate for agents.
⚡ Reliability
Best When
You need a flexible, developer-friendly headless CMS with real-time capabilities and strong agent/AI integration support.
Avoid When
Your team lacks JavaScript expertise to customize Sanity Studio, or you need a fully managed UI with no code.
Use Cases
- • Querying structured content with complex GROQ expressions
- • Real-time content collaboration with live preview
- • AI-assisted content creation and editing via MCP
- • Building composable content architectures for enterprise apps
- • Programmatic content migration and transformation
Not For
- • Simple content needs where GROQ learning curve isn't justified
- • Teams unfamiliar with JavaScript/React (Studio requires customization)
- • Projects needing a traditional SQL/relational data model
Interface
Authentication
Project-level tokens with read, write, or manage roles. Robot tokens for agent use. Token permissions are coarse-grained at the project level.
Pricing
Generous free tier. Self-hosted Sanity Studio is open source; the Content Lake is the SaaS component with pricing.
Agent Metadata
Known Gotchas
- ⚠ GROQ is Sanity's custom query language - agents must learn it rather than using standard SQL or GraphQL
- ⚠ Real-time listeners use WebSocket connections that require different handling than REST polling
- ⚠ Mutations use a transaction format (array of operations) rather than single-operation REST calls
- ⚠ Draft documents have a 'drafts.' prefix on their ID - agents querying published content must exclude drafts
- ⚠ Image and file asset uploads are separate from document mutations and require two-step process
