## What it does

Your agent names a path like `my-project/2026-07-07-error-report.md` and the server sends that file to the hosted md-log service. Folders that don't exist yet get created. Every save lands as a new immutable version, so the edit history stays readable.

There are 17 tools. The headline one is `save_markdown`: it creates or overwrites a file, uploading embedded images first and swapping placeholders for `asset://` links. `edit_markdown` handles literal replacements inside a file, `append_to_markdown` adds to the end. Both use optimistic concurrency via `base_version_no` and retry once on a conflict.

You need Node 22+ and a Personal Access Token from the md-log web app (the tokens section of settings; it's shown once). No token, no backend calls. Two ways to connect: the hosted HTTP endpoint at `https://mcp.md-log.com/mcp`, or local stdio through `npx -y md-log-mcp`.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `MDLOG_API_BASE_URL`, `MDLOG_PAT` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- save an agent report as markdown at a chosen path
- upload screenshots alongside the text and get `asset://` links back
- append a new section to an existing report without rewriting it
- replace one exact fragment and leave the rest untouched
- roll a file back to an earlier version

## Example prompts
- Save the error report to `my-project/2026-07-07-error-report.md`
- Append a conclusions section to the end of the report
- Replace the version line in the report with the current one
