Alttext tools (12, 4 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • bulk_createwrite action

    Upload a local CSV file from the MCP server machine and queue asynchronous alt-text generation using account credits. The response does not confirm generation completion. CSV should have columns: url (required), asset_id, lang, keywords, tags, metadata (optional).

  • delete_imagewrite action

    Delete an image from your AltText.ai library

  • generate_alt_text

    Generate AI-powered alt text for an image URL. Returns the result synchronously (may take a few seconds). Uses account credits; additional languages and image conversion can increase the total. Can overwrite existing alt text when requested.

  • generate_alt_text_from_file

    Generate alt text from a local image file. Reads a file on the MCP server machine and uploads it to AltText.ai. Uses account credits; additional languages and image conversion can increase the total. Can overwrite existing alt text when requested.

  • get_account

    Get your AltText.ai account info including credit balance, usage, and settings

  • get_image

    Get details for a specific image by its asset ID

  • list_images

    List images in your AltText.ai library with pagination

  • scrape_page

    Find images on a web page and queue alt-text generation jobs. Uses account credits. Images are processed asynchronously; inspect the image library for results.

  • search_images

    Search images by alt text content

  • translate_image

    Add alt text in a new language for an existing image. Uses the asset_id to find the image and generates a translation. Uses account credits for each newly generated language.

  • update_accountwrite action

    Update your AltText.ai account settings (name, webhook URL, notification email)

  • update_imagewrite action

    Update alt text and/or metadata for an existing image

Install Alttext in Claude Code, Cursor or VS Code

Runs npx -y @alttext_ai/alttext-mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Alttext repository's README, as published. We do not edit it. Read it on GitHub

AltText.ai MCP Server

An MCP server that lets AI assistants generate alt text, manage image libraries, and queue alt text generation for web page images using the AltText.ai API.

Works with Claude Desktop, Claude Code, Cursor, Windsurf, and any MCP-compatible client.

Verify this package

This server runs npx -y @alttext_ai/alttext-mcp, which downloads and executes code with your API key in its environment. That's worth a moment of verification before you install — by you or by an AI agent doing the setup. Everything below should match:

The npm scope is @alttextai (with an underscore), while the GitHub org is alttextai (no underscore). This is intentional, not a typosquat: the @alttextai npm scope was already taken, so we publish under @alttextai. The two names refer to the same official AltText.ai package.

To cryptographically verify the published package was built by this repo's CI — not just trust the metadata — run:

npm audit signatures

from a project where the package is installed. This validates the registry signature and the npm provenance attestation, which links the tarball to a specific commit and GitHub Actions build. A counterfeit package can forge repository.url and other metadata, but it cannot forge the provenance attestation — so this is the check that actually matters.

(For a quick, weaker cross-reference of the claimed source you can run npm view @alttext_ai/alttext-mcp repository.url, but note that field is publisher-controlled metadata and proves nothing on its own.)

Pinning a version

The setup snippet uses npx -y @alttext_ai/alttext-mcp, which always resolves to the latest published version and re-runs it on every launch. That keeps you current, but it also means a future release runs automatically without review. If you want a reproducible, audited install, pin a specific version:

"args": ["-y", "@alttext_ai/alttext-mcp@1.0.5"]

Run npm audit signatures against the pinned version, and bump it deliberately when you're ready to take a new release.

Setup

Requirements: Node.js 22+ and an AltText.ai API key

Add the server to your MCP client configuration:

{
  "mcpServers": {
    "alttext-ai": {
      "command": "npx",
      "args": ["-y", "@alttext_ai/alttext-mcp"],
      "env": {
        "ALTTEXT_API_KEY": "your-api-key"
      }
    }
  }
}
