Mcp Sanity Images— agent skill

<p align="center"> <img src="logo.svg" alt="MCPi sanity-images" width="280" /> </p>

<p align="center"> MCP server for uploading local images to <a href="https://www.sanity.io/">Sanity CMS</a>. <br/> Lets AI assistants upload files from your filesystem directly into Sanity as image assets. </p>

Quick Start

1. Get your Sanity token

Either set the SANITY_TOKEN env var, or just log in with the Sanity CLI:

npx sanity login

The server reads the token from the Sanity CLI config automatically (~/.config/sanity/config.json on all platforms).

2. Add to Claude Code

claude mcp add sanity-images --scope user --transport stdio \
  -e SANITY_PROJECT_ID=your-project-id \
  -- npx -y mcp-sanity-images@latest

That's it. Restart Claude Code and the tools are available. Every session runs the latest version automatically.

Also works with bunx mcp-sanity-images@latest if you have Bun.

Tools

Supported formats: PNG, JPG/JPEG, WebP, GIF, SVG.

Configuration

All tools also accept projectId and dataset as parameters, overriding the env vars per-call.

Tool Details

upload_image

Upload a single file and get back the asset reference.

filePath: "/path/to/hero.png"
alt: "Hero banner"  (optional — derived from filename)

Returns { assetId, url, alt, reference } — the reference is ready to patch onto any Sanity image field.

upload_and_set

Upload + patch in one call.

filePath: "/path/to/hero.png"
documentId: "product-123"      # or "drafts.product-123" to patch the draft
fieldPath: "hero.image"

Before uploading, the tool checks which of <id> and drafts.<id> exist, so a wrong ID uploads nothing:

The response's documentId is the document actually patched. Mutations are sent with returnIds=true&visibility=sync, so a follow-up groq_query sees the change.

batch_upload

Upload all images from a directory.

directory: "/path/to/images"
recursive: true

Returns { uploaded, assets }. If some files fail, the rest still upload and the failures are listed in failed (with failedCount).

list_images

List image files without uploading — useful for the AI to see what's available.

directory: "/path/to/images"
recursive: true

groq_query

Run any GROQ query (read-only). Long queries are sent via POST automatically. Useful to find document IDs before using upload_and_set.

query: "*[_type == 'product']{_id, title, slug}"
perspective: "raw"   # optional: raw (default) | published | drafts

The server pins Sanity API version v2025-02-19. That version made published the API's default perspective. This tool sends raw unless you ask otherwise, so results match what earlier releases (API v2021-10-21, default raw) returned.

Updates

Using `npx @latest` (recommended): You always get the latest version — no manual updates needed.

Using a binary: The server checks for new releases on startup and logs to stderr if outdated:

[mcp-sanity-images] WARN v0.5.0 available (current: v0.4.1). Download: https://github.com/pijusz/mcp-sanity-images/releases/latest

Check your installed version:

mcp-sanity-images --version

To update, download the new binary and replace the old one.

Development

Requires Bun.

git clone https://github.com/pijusz/mcp-sanity-images.git
cd mcp-sanity-images
bun install
bun test
bun run lint      # biome check
bun run build     # compile standalone binary
