AltTextGeneratorAI MCP Server
Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| ALTTEXTGENERATORAI_API_KEY | No | Your AltTextGeneratorAI API key. Required for generating alt text and checking credits; audit_page without `generate` works without it. | |
| ALTTEXTGENERATORAI_ALLOWED_DIR | No | If set, generate_alt_text_from_file only reads image files inside this folder. | |
| ALTTEXTGENERATORAI_API_BASE_URL | No | Override the API address (for testing). Must be https, or http on localhost. Default https://alttextgeneratorai.com/api | https://alttextgeneratorai.com/api |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| generate_alt_textA | Writes SEO-friendly, accessible alt text for one image that is available at a public http(s) URL. Uses 1 credit from the AltTextGeneratorAI account. |
| generate_alt_text_from_fileA | Writes SEO-friendly, accessible alt text for an image file on this computer (JPEG, PNG, GIF or WebP, up to 3 MB). Uses 1 credit from the AltTextGeneratorAI account. |
| check_creditsA | Shows how many credits are left on the AltTextGeneratorAI account. Each generated alt text uses 1 credit. |
| audit_pageA | Reads a public web page and lists the images that have no alt attribute (missing) or an empty one (empty, which is correct for purely decorative images). This is free by default. Set generate to true to also write suggested alt text for the images found, which uses 1 credit per image. |

Scored across 4 tools
Each tool targets a distinct function: URL-based generation, local-file generation, credit checking, and page auditing. The two generation tools are differentiated by input source (public URL vs. local file), which is a clear criterion, though their near-identical names require reading the description to be sure.
All four tools use consistent snake_case with a verb-first pattern (generate_alt_text, generate_alt_text_from_file, check_credits, audit_page). The shared prefix on the two generators is a deliberate, readable grouping rather than an inconsistency.
Four tools is a tight, well-scoped set for an alt-text service; each tool covers a distinct capability and none feels redundant. Nothing appears padded or missing at the structural level.
The surface covers the core lifecycle: generate from URL, generate from file, audit a page for missing/empty alt text, and check remaining credits. Minor gaps exist around batch processing of multiple images or applying suggested alt text back to a page, but agents can work around these via per-image calls.
