- AlicenseNot gradedqualityCmaintenanceA local-first CLI and MCP server that helps you build and search a personal knowledge vault from Markdown notes, with semantic search and AI-powered features like stale note detection and session memory harvesting. It’s provider-agnostic, requires no GPU in its default mode, and exposes your vault as long-term memory to any MCP-compatible AI tool like Claude Code.62 PyPI47Apache 2.0
- AlicenseNot gradedqualityCmaintenanceLocal-first MCP server for indexing and searching research materials (papers, notes, logs, READMEs) using SQLite FTS, with tools for memory management and evidence retrieval.MIT

- AlicenseNot gradedqualityBmaintenanceGives AI agents a long-term memory layer over plain Markdown notes, letting them run ranked, citable searches, record new facts, and inspect conflicts and stale entries. Results carry freshness labels, supersession history, and audit fields like search timestamp and no-match status so agents can prove a search actually ran.MIT
- AlicenseAqualityBmaintenanceEnables users to create, retrieve, update, delete, and full-text search a local knowledge base of notes persisted in SQLite with FTS5, exposed over stdio or authenticated Streamable HTTP. It also surfaces recent/single-note resources and prompts for summarizing notes and drafting replies.5MIT
- AlicenseAqualityBmaintenanceQueryable second brain over your notes, docs, PDFs and chat exports — hybrid retrieval, cited answers, MCP server included949 PyPI100MIT
- AlicenseBqualityAmaintenancePersonal multi-LLM memory repository using Markdown as source of truth, SQLite FTS5 for retrieval, and MCP tools for search, context, and write proposals.74Apache 2.0
- AlicenseNot gradedqualityBmaintenanceLocal-first markdown vault with a built-in MCP server (streamable HTTP). 16 tools and 2 resources for Claude Code / Desktop / Cursor: read/write/search plus context_for_query, find_orphans, weekly_digest, compare_notes, semantic_outline. Per-folder agent permissions, LanceDB vectors, local Xenova ONNX embedder swappable to Ollama. Single Bun binary. AGPL.33AGPL 3.0
- AlicenseNot gradedqualityBmaintenanceProvides a local-first, long-term memory service that lets AI agents and humans save, search, and retrieve Markdown notes across sessions with full-text BM25 retrieval and source-attributed evidence snippets.2MIT

Scored across 4 tools
The four tools are largely distinct: ask generates answers, check validates the agent's own claims, verify detects drift on stored beliefs, and corpus reports index contents. The ask/check boundary and check/verify boundary could be momentarily confused since all involve citation judgment, but descriptions explicitly cross-reference each other and clarify intent.
All four tools use the same chamber_<verb> prefix pattern (chamber_ask, chamber_verify, chamber_check, chamber_corpus). Fully predictable and consistent.
Four tools is a tight, well-scoped set for a citation-grounded Q&A/verification system, with each tool covering a distinct operation. It is on the lean side but nothing feels redundant or missing at the count level.
Core workflows (ask, self-check, drift verify, corpus introspection) are covered, but there is no tool to ingest/re-index notes despite check and verify depending on re-ingestion, and no way to inspect stored beliefs or citation debt directly. These are notable gaps an agent would hit when trying to manage the corpus lifecycle.
