WikiMCP

What it does

WikiMCP transforms the way AI handles knowledge by moving away from transient RAG chunks to a persistent, compounding personal wiki. Instead of re-deriving knowledge every session, the AI incrementally builds and maintains a structured collection of interlinked markdown files, effectively creating a long-term memory that evolves with every conversation.

Tools

• wiki_info: Provides wiki stats and schema instructions to the AI at session start.
• read_index: Accesses the master catalog of all wiki pages.
• update_index: Updates the master catalog and auto-commits to git.
• write_page: Creates or overwrites a wiki page with auto-commit.
• read_page: Retrieves content from a specific wiki page.
• list_pages: Lists all pages or those within a specific subdirectory.
• search_wiki: Performs full-text search across the entire wiki.
• append_log: Adds timestamped entries to the activity log.
• delete_page: Removes a wiki page and auto-commits.
