Cogvault Overview

The cogvault MCP server indexes plain Markdown files into a local SQLite-backed search index for agent memory. It combines semantic and BM25 keyword retrieval with rank fusion, optional temporal decay, MMR, and one-result-per-card behavior. FastEmbed generates embeddings locally, so indexing and retrieval do not require an LLM or network service. Use it when agents need private, deterministic recall from separate memory directories.

Primary Use Cases for Cogvault:

Index existing Markdown memory for agent recall
Separate memory directories across multiple agents
Search deployment decisions and bug fixes offline
Measure recall quality with real agent queries
