Add free PDF, OCR and Office conversion tools to claude.ai and ChatGPT with one MCP connector

Tanod launched a hosted MCP server at tanod.dev/mcp/docs that exposes 39 document-processing tools — including PDF extraction, OCR, Office-to-PDF conversion, table extraction, and form filling — as a custom connector for claude.ai and ChatGPT with no API key, account, or OAuth required. Document calls from the two chat apps draw on a shared free pool of 2,000 calls per day, after which tools return a USDC price quote settled via x402 on Base or Polygon, with heavy conversions such as OCR and Office-to-PDF priced from USD 0.01 per call. Tanod says it does not store request bodies or results, though server logs including IP addresses are kept for up to 30 days.

Chat apps are good at reading text you paste in. They are much less reliable at working on actual files: pulling clean Markdown out of a PDF, running OCR on a scan, merging or splitting documents, converting a Word file to PDF, or lifting a table into a spreadsheet. A remote MCP server can fill that gap, because the app calls a tool and gets a real file or structured result back. Tanod is a hosted MCP server. Its document route, https://tanod.dev/mcp/docs , exposes 39 tools and works as a custom connector in claude.ai and ChatGPT. It needs no API key, no account and no OAuth. extract pdf , convert document to markdown pdf ocr , ocr image convert office to pdf , convert pdf to word , html to pdf , images to pdf , pdf to images extract pdf tables , convert excel to json , convert bank statement pdf merge , pdf split , pdf extract pages , pdf remove pages , pdf reorder pages , pdf rotate , pdf crop , pdf resize pdf form fields , pdf fill form , pdf flatten , pdf outline , pdf set outline , pdf metadata , pdf attachments pdf page numbers , pdf watermark , pdf compress , pdf protect , pdf unlock , pdf repair build xlsx workbook , build pptx deck , fill docx template pdf inspect , pdf pipeline , pdf rasterize tanod and paste https://tanod.dev/mcp/docs . On Team and Enterprise plans, an owner adds it under Organization settings Connectors, and members then connect it. @ and pick it. Account and workspace policies decide whether you can add custom servers at all. Settings screens change often; the URL and the transport streamable HTTP, no authentication are what matter. The sample files are public, so you can test without uploading anything. For merge, split or form filling, give the assistant two or more document URLs and say what you want, for example "merge these two PDFs and add page numbers". Document calls from claude.ai and ChatGPT draw on a shared free pool of 2,000 calls a day. The pool is shared across all connector traffic from those two apps, not per user. Remote connectors are called from the vendors' servers, which share IP ranges, so a per-IP allowance would run out for everyone at once. That means the pool can run out. When it does, a tool returns a price quote in USDC instead of a result, and nothing is charged unless your client pays it. The per-call price then applies, settled with x402 in USDC on Base or Polygon. Chat apps do not sign x402 payments, so past the pool you would call from an x402-capable client such as the Tanod SDKs. Heavy conversions such as Office to PDF and OCR are priced from USD 0.01 per call when called outside the shared pool. Pricing details are at https://tanod.dev/pricing/ https://tanod.dev/pricing/ . From the privacy policy: "We do not store request bodies or results, with two exceptions that speed up repeat requests: the address and chain of contracts you ask us to scan, and a fingerprint of scanned packages." Per call, Tanod records the time, endpoint, result status, price and a coarse client type. Server logs include your IP address and are kept for up to 30 days. Free-tier counters are kept per IP address per UTC day. Full text: https://tanod.dev/privacy/ https://tanod.dev/privacy/ tools/list method on the endpoint.
