Mdkit

Convert documents (PDF, Office, HTML) into clean, LLM-ready Markdown and JSON.

mdkit converts documents — PDF, Word, PowerPoint, Excel and HTML — into clean, LLM-ready Markdown and JSON over a simple REST API and an MCP server, so developers can feed real-world documents straight into a model or a RAG pipeline without hand-cleaning them. Small files convert synchronously in one call; larger jobs run through an async job queue with polling and signed webhooks. Free tier to try it, metered credits for volume. An alternative to Jina Reader, Firecrawl, Docling, MarkItDown and Unstructured.

MCP server

Streamable-HTTP endpoint: https://api.mdkit.online/mcp/ — the anonymous tier works without a key; an API key raises the limits.
