Overview

AI-generated overview

Hosted MCP server that converts PDF, Word, PowerPoint, Excel and HTML documents into Markdown, with an OCR queue for large or scanned files.

What you can do
  • Convert PDF, Word, PowerPoint, Excel and HTML files to Markdown in a single call (files up to 8 MB)
  • Send larger or scanned documents (up to 25 MB and 200 pages) through an OCR queue with table detection
  • Retrieve queued results as Markdown plus a JSON structure file, by polling or a signed webhook
When to use it
Useful when an assistant needs to read or quote content from office documents and PDFs, including scanned ones, and turn it into Markdown for summarising, searching or further processing.
Requirements
Remote streamable-HTTP endpoint; no local install. The anonymous tier works without credentials; an optional X-API-Key header raises limits. Files are uploaded to the provider's servers, which are located in Germany.
Before you install
Documents are uploaded to a third-party service, so avoid sending confidential material unless that is acceptable. The free plan is limited to 100 credits a month and paid plans exist; check pricing before relying on it. An API key is passed in the X-API-Key header.

Installation

In SourceWeft

  1. Open flatmark in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.flatmark%2Fflatmark/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

flatmark

Document to Markdown API and MCP server for PDF, Word, PowerPoint, Excel and HTML. OCR queue for large files. Hosted in Germany.

flatmark converts PDF, Word, PowerPoint, Excel and HTML to Markdown over a REST API and an MCP server. Files up to 8 MB convert in one call with MarkItDown. Files up to 25 MB and 200 pages go through a queue that runs Docling with OCR and table detection. The queue returns Markdown and a JSON structure file, by polling or a signed webhook. The servers are in Germany. The free plan has 100 credits a month and needs no card.

Quickstart

Convert a PDF to Markdown in one call. The anonymous tier needs no key; add -H "X-API-Key: $FLATMARK_API_KEY" for your plan's limits.

sh
curl -sO https://flatmark.dev/app-static/samples/sample.pdfcurl -F [email protected] https://api.flatmark.dev/v1/convert
json
{"markdown":"Hello Docling smoke test\n\n","meta":{"filename":"sample.pdf"}}

Files over 8 MB and scanned documents go through the OCR queue instead: POST /v1/convert/jobs, then poll or receive a signed webhook.

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
