Obsidian Wiki MCP
Supports UIby aud1ence
Implements Karpathy's LLM Wiki pattern to solve document drift in Obsidian vaults.
What it does
Connects an AI assistant to an Obsidian vault to implement a structured knowledge-base pattern. It acts as a pure storage and retrieval layer, allowing the LLM to decide what to write and how to synthesize information, effectively preventing document drift as knowledge evolves across sessions.
Tools
wiki_init: Initializes the Obsidian vault for use as an LLM wiki.wiki_write_page: Writes or updates a page in the wiki.wiki_query: Search and retrieve information about specific topics from the vault.wiki_apply_fix: Updates specific parts of a page using unified diffs.
