# ManualesGratis - AI Resource Hub > ManualesGratis is an SEO-first platform for AI tools, prompts, MCP servers, manuals, articles, and links. ## Content Available - AI Tools directory: tools and services for AI - Prompt Library: curated prompts for Claude, ChatGPT, Midjourney, and more - MCP & Skills: MCP servers, plugins, and extensions - Manuals: technical manuals and guides - Articles: tutorials and guides - Links: curated resource links ## Markdown for Agents Every content page serves a clean Markdown rendition through content negotiation. Send `Accept: text/markdown` to any page URL and you get Markdown instead of HTML; browsers and crawlers keep getting HTML. Responses carry `Vary: Accept` and an `x-markdown-tokens` estimate so you can budget context before reading. Covered: the home page, the six listings (`/ai-tools`, `/prompts`, `/mcp-skills`, `/articles`, `/manuals`, `/links`, plus `?page=N` and the `/ai-tools/for/:audience` and `/prompts/for/:audience` variants), and every detail page. Pages with no Markdown rendition (sign-in, account, admin) simply return HTML. Limit: 60 Markdown requests per minute per IP. For bulk reads use the API below. ## AI Content API Machine-readable content is available at `/api/llm/content` endpoint.
