Page Tree Cache

The server maintains a local tree cache (tree.yaml) that maps your wiki's section hierarchy. This cache is used by get_tree and suggest_placement to help with page navigation and placement.

Auto-sync: The cache updates automatically when you create, update, delete, or clone pages through the MCP tools.

Manual refresh: Use refresh_tree_cache("root-slug") to rebuild the cache from the API. This fetches all descendant pages and their titles.

# First time — initialize cache from your wiki root
refresh_tree_cache("your-root-slug")

# Quick check — read from cache (instant)
get_tree()

# Force fresh — bypass cache and fetch from API
get_tree(use_cache=false)

# Reset — clear and re-fetch
clear_tree_cache()
refresh_tree_cache("your-root-slug")

Markdown to YFM Converter

Yandex Wiki uses YFM (Yandex Flavored Markdown), which differs from standard Markdown. The converter handles:

Markdown	YFM
| H1 | H2 | tables	#| || |# wiki tables
> [!NOTE] callouts	{% note info %}
<details><summary>	{% cut "Title" %}
<u>text</u>	++text++
<mark>text</mark>	==text==
<sup>text</sup>	text^super^
<sub>text</sub>	text~sub~
