Free read-only checks for evidence of AI use in text, links, images, saved prompts and C2PA.
Scored across 6 tools
The tools mostly target distinct inputs and outputs: text detection, image detection, URL/page checking, X reply estimation, saved prompt extraction, and C2PA credential reading. There is some overlap because check_image already reads C2PA and saved prompts, and check_url can also analyze an image URL, which may make an agent wonder whether to use the specialized tools.
All tools use a consistent snake_case verb_noun or verb_object pattern (check_image, check_text, check_url, estimate_x_ai_replies, extract_saved_prompt, read_content_credentials). The naming is predictable and readable throughout.
Six tools are well-scoped for an AI-content detection server, with each tool covering a distinct surface: image, text, URL, X replies, saved prompts, and content credentials. There is no obvious redundancy or missing core capability that would require a larger set.
The surface covers the main AI-detection workflows: image, text, URL, social replies, prompt extraction, and provenance credentials. Minor gaps remain, such as no dedicated AI-likelihood detection for video/audio (only credential reading) and no batch or account-level operations, but these are reasonable omissions.
AI image detector: check an image (PNG, JPEG, WebP, AVIF or single-page TIFF, up to 20 MiB) by public URL or base64. Reads the evidence in the file first (C2PA Content Credentials naming the generator or camera, IPTC AI labels, prompts saved by Stable Diffusion tools, EXIF), then adds an AI-likelihood score from the image detector. Use for: is this photo real or AI, is this a deepfake, was this made with Midjourney, DALL-E, Firefly or ChatGPT? A score is an estimate; records are evidence. No public report is created. Docs: https://isgenai.com/developers/mcp
Inputs: url, file_name, image_base64.
AI text detector: check pasted text or code (up to 16,000 characters, 30 languages) for AI. Returns an AI-likelihood score with the reasons behind it (300+ characters, about 100 for Chinese, Japanese or Korean), flags chatbot leftovers such as ChatGPT citation tags and unfilled placeholders, and quotes any statement of AI use or named AI tool (ChatGPT, Claude, Gemini, Copilot) word for word. Use for: is this essay, email, post, review or code written by AI or ChatGPT? A score is an estimate, not proof of authorship. Private: no public report is created. Docs: https://isgenai.com/developers/mcp
Inputs: text (required), kind.
Check a public web page or file URL for AI: fetches it and reads AI labels, AI-use statements, Content Credentials and saved creation records found there, with an AI-likelihood score for the image. Use for: is this article, news photo, product image or social post AI-generated or fake? Logins, paywalls and CAPTCHAs are not bypassed. No public report is created. Docs: https://isgenai.com/developers/mcp
Inputs: url (required).
Estimate what share of the replies under an X (Twitter) post look AI-generated or bot-driven. Pass the reply texts with any author details (handle, bio, followers, following, joined date, default avatar) and timestamps you have; the post text and time sharpen the estimate. Returns the percentage, a band and a 0-100 score with signals for every reply. An estimate from patterns, not proof about any account. Docs: https://isgenai.com/x-ai-replies
Inputs: replies (required), post.
Read the prompt, negative prompt, model and settings saved inside an image by AUTOMATIC1111, ComfyUI (including Flux workflows), InvokeAI or NovelAI. Only reads records stored in the file; it never reconstructs or guesses a prompt. Screenshots and re-uploads usually remove these records. Docs: https://isgenai.com/developers/mcp
Inputs: url, image_base64.
Read C2PA Content Credentials from an image, video, audio or PDF file (by public URL or base64, up to 20 MiB). Reports the manifest, recorded actions and digital source type, with cryptographic validation and signer trust as separate findings. Docs: https://isgenai.com/developers/mcp
Inputs: url, file_name, media_type, file_base64.
