- AlicenseNot gradedqualityAmaintenanceDescription: Persistent local memory for Claude, Cursor and Codex. 13 MCP tools, SQLite + FTS5 + Knowledge Graph. No cloud, no API keys. One command: npx @studiomeyer/local-memory-mcp.31 npm15MIT
- AlicenseNot gradedqualityAmaintenanceLocal-first, file-based memory layer for AI agents — one shared Markdown vault across Claude, Codex, Gemini, Cursor and any MCP client. Provides read/write memory tools with an audit trail, per-agent trust levels, and Git sync; no cloud and no lock-in.2MIT
- AlicenseNot gradedqualityAmaintenanceLocal-first, source-grounded memory for AI agents, with citations, bitemporal history, review-gated corrections, and MCP tools for search and recall.36 PyPI3Apache 2.0
- AlicenseNot gradedqualityAmaintenanceProvides a local-first, source-cited memory layer for AI agents, with MCP tools to search, read, explain sources, and propose/apply memory updates.26 npm13Apache 2.0
- AlicenseNot gradedqualityAmaintenanceLocal memory for AI agents in one SQLite file on your own machine. Facts carry a validity window and a confidence score, so an outdated one is superseded and downweighted rather than deleted, and retrieval fuses BM25, vector similarity and a knowledge graph.2Business Source 1.1

- AlicenseNot gradedqualityAmaintenanceGives coding agents a persistent memory by searching a local, read-only index of existing markdown and letting them write findings back as notes that the next session can retrieve. It serves ranked, context-sized results over MCP, injects standing conventions at session start, and keeps data on your machine with secret redaction and archive-only deletion.142 PyPIMIT
- FlicenseNot gradedqualityAmaintenanceEnables AI agents to search and query a local knowledge base of scattered notes and docs through hybrid vector plus BM25 retrieval with section-level citations, and to store, retract and explore durable memories, note links and agent harness memories. It also exposes note resources plus briefing, study-plan and contradiction-check prompts, all backed by a shared local index.-
- AlicenseAqualityAmaintenanceLocal memory for AI agents over plain Markdown files: hybrid vector + BM25 recall (RRF), one isolated memory per agent directory, fully offline with no LLM in the loop. Tools: cogvault_recall and cogvault_record.2129 PyPI1MIT
- FlicenseNot gradedqualityAmaintenanceGives AI coding agents direct, local-first read/write access to persistent memory — project decisions, preferences, error patterns, research, and cross-project guidelines — retrieved by semantic search backed by SQLite with no API keys or network calls. A companion server also exposes optional autonomous task-queue execution.-
- AlicenseAqualityAmaintenanceEnables multiple AI agents on one machine to write, search, fetch, link, and give feedback on a shared local store of Markdown-backed facts, preferences, and conventions that persists across sessions. Memories gain confidence as different hosts confirm their use and can be distilled into denser ones, so agents stop re-discovering the same context.5598 PyPI1MIT
- AlicenseNot gradedqualityAmaintenanceLocal Markdown memory for AI agents with multilingual BM25 retrieval (optional semantic fusion). Search, recall, write, archive and curate notes in a vault you choose via the mnemosyne-mcp server.132 PyPI11MIT

Scored across 25 tools
The tools span many distinct resources and actions, and descriptions explicitly clarify overlapping retrieval tools like memory_query vs memory_ask. However, some residual overlap exists between memory retrieval and resonance reading, causing slight hesitation in selection.
Every tool uses the mnemosyne_ prefix and snake_case consistently, with no case mixing or inconsistent verb styles. The resource-oriented naming pattern is predictable throughout, with only minor deviations like 'about'.
At 25 tools, the set is heavy for a single MCP server, sitting at the upper bound of the 16-25 borderline range. While each tool appears to serve a distinct purpose, the volume risks overwhelming an agent.
The surface covers memory creation and retrieval, full calendar and todo CRUD, agent session inspection, Pheme radar and watch management, and cockpit updates. Gaps include no memory update/delete, no direct memory get by ID, and no agent-triggered Pheme scan or dream cycle, though some may be intentional.
