flatmark missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

conversion

get_conversion_job

Check a queued conversion job you submitted. Returns `job_id` and `status` (`queued`, `running`, `succeeded` or `failed`). A succeeded job includes the `markdown` when it is under 100 KB, otherwise a `result_url` to download it (also free). A failed job includes `error`, one sentence with the reason. Results are deleted 7 days after submission. An expired result is reported in `error`. Requires an API key. Credits: free. This tool is not metered.

convert

convert_document

Convert a document up to 8 MB to Markdown and return it directly. Pass the file as base64 in `content_base64`, or as a download link in `file`, and its name in `filename`. The extension decides the type: .pdf, .docx, .pptx, .xlsx, .html, .htm or .txt. Returns `markdown` and `meta` (`filename`, `length` in characters). PDFs come back as plain text without headings and without OCR. For scans, tables and page numbers, use `submit_conversion_job`. Works without an API key at the anonymous rate limit. Credits: 1 per call.

submit

submit_conversion_job

Queue a document up to 25 MB and 200 pages for conversion with OCR and tables. Pass the file as base64 in `content_base64`, or as a download link in `file`, and its name in `filename` (.pdf, .docx, .pptx, .xlsx, .html, .htm or .txt). Returns `job_id`, `status` and `result_url`. Call `get_conversion_job` with the `job_id` until `status` is `succeeded` or `failed`. A conversion may take up to about 2 minutes. Optional `webhook_url`: a public http or https URL that receives a POST with the job's final state. The request carries `X-Appkit-Signature: sha256=<hex>`, an HMAC-SHA256 of the raw body keyed with the returned `webhook_secret` (shown only once). 3 delivery attempts. Requires an API key. The credits are refunded if the job fails. The uploaded file is deleted when the job finishes. Results are kept for 7 days after submission. Credits: 10 per call.

flatmark — questions

Answers built from our own checks of this server.

What can flatmark do?

It exposes 3 tools, read directly from the server on our last check. Among them: convert_document, get_conversion_job, submit_conversion_job. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is flatmark working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 234 ms. The bar chart above shows every period we have measured.

How do I connect flatmark?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does flatmark need an API key?

No. flatmark completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is flatmark?

It answers our handshake in 234 ms on average, which is faster than 57% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is flatmark open source?

Yes — it is published under the MIT licence and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
