For AI agents and developers

AI assistants are welcome to use ainsfw.tools data. Everything on this page is free, read-only and needs no API key. It exposes the same information as the website: platform scores, free tier limits, prices together with their billing terms, features, comparisons and the characters in our index. Like the site itself, all of it is strictly for adults.

MCP server

Address: https://ainsfw.tools/mcp. Transport: Streamable HTTP, stateless, no sign-in. Server card: /.well-known/mcp/server-card.json.

• list_platforms: Returns the adult (18+) AI chat platforms reviewed on ainsfw.tools, ordered by editorial score (the mean of six criteria, each rated 1 to 10). You can filter on free tier, budget, feature or explicit content and sort by rank, by how generous the free tier is, or by price. Each result includes the score, free tier, cheapest price with billing, what the platform suits best and a link to the review.
• get_platform: The full ainsfw.tools record for a single NSFW AI chat platform: rank, overall score and six sub-scores, company, free tier limits, paid plans with billing, features, explicit content policy, pros, cons, best-for notes, the date prices were checked, our dated hands-on test of the free tier (free messages, filter, reply time, memory), and links to its review, characters and comparisons.
• compare_platforms: Puts two NSFW AI chat platforms reviewed by ainsfw.tools next to each other: scores, free tiers, prices, explicit content policy and features, along with which one scores higher and a link to the comparison page.
• search_characters: Looks up characters that ainsfw.tools indexes from its platforms (adults only, screened to exclude minors, real people, non-consent and incest). Filter by name or description words, platform, category tag, gender and art style. Each hit returns the character, its platform, a short hook, its profile page and a portrait.
• list_categories: Lists the character categories (tags) on ainsfw.tools with a character count for each, grouped by type (personality, relationship, looks, genre, kinks and themes, style, gender). Pass the slug to search_characters.
