Tools & Capabilities Breakdown

Md Log MCP Tools (14)

upload_asset

Upload one image (reserve → presigned PUT → complete) and return an `asset://<key>` reference to embed as `![alt](asset://<key>)`. Provide the image as **either** `data_base64` (inline base64) **or** `file_path` (a local file the server reads) — exactly one; with `file_path`, `filename` defaults to…

append_to_markdown

Append to an existing file with optimistic concurrency (GET current → concat → conditional PUT with `base_version_no`). Auto-retries once on conflict, then surfaces `CONFLICT`. Accepts `commit_message` — a recommended 1-2 line change summary shown in the version history.

update_markdown

Replace a file's content. Pass `expected_version` for optimistic concurrency (mismatch → `CONFLICT`); omit it to force LWW. Accepts `commit_message` — a recommended 1-2 line change summary shown in the version history.

get_markdown

Read a file's content by path (materializes inline content or a presigned content URL for large docs). Pass `version` (a `version_no` from `list_versions`) to read an old immutable version.
