Knowledge & Memory
SummaryLocal-first persistent memory for AI agents. SQLite + local embeddings (all-MiniLM-L6-v2), hybrid semantic + FTS5 recall, secret detection, and contradiction handling. 6 MCP tools (remember, recall, forget, feedback, context, status) over stdio. Zero cloud, no API keys, fully offline. Works with Claude Desktop/Code, Cursor, and Windsurf. npm install -g @hbarefoot/engramAuditable context control plane and MCP server for AI coding agents. Compresses context 70–95% (BM25 + entropy + dep-graph knapsack), stabilizes prompt prefixes for provider cache discounts, routes easy tasks to cheaper models (RAVS Bayesian router), and verifies answers locally with WITNESS hallucination guard (0.844 AUROC, $0, 3 ms). MemoryOS adds local budget-aware working/episodic/semantic memory with decay, safety scanning, and durable persistence. 38 agent integrations (Cursor, Claude Code, Codex, Aider, and more). Ships as MCP server (entroly serve), HTTP proxy, or Python/Rust library. Apache-2.0, local-first. pip install entroly

Tools & Capabilities Breakdown

Engram Tools (6)

engram_remember
Store a memory with category, entity, confidence, namespace, tags. Auto-runs secret detection.
engram_recall
Hybrid semantic + FTS5 search. Supports `category`, `namespace`, `threshold`, and `time_filter`.
engram_forget
Delete a specific memory by ID.
engram_feedback
Vote a memory helpful/unhelpful. Drives the feedback loop above.
engram_context
Pre-formatted context block (`markdown` / `xml` / `json` / `plain`) with a token budget for system-prompt injection.
engram_status
Health check: memory count, model status, configuration.

Entroly Tools (6)

Recoverable compression using BM25, entropy, and dependency graph knapsack
Auditable receipts detailing context kept and discarded
Local hallucination detection with WITNESS guard
Budget-aware memory with decay and durable persistence
Routing tasks to cheaper models via Bayesian router
Supports 38+ AI agent integrations and multiple deployment modes
