Persistent memory + FTS5 full-text search for Claude Code conversation history. Indexes `~/.claude/projects/` JSONL into SQLite, exposes 10 MCP tools (store/recall/search memories, list sessions, get summaries) plus prompts. Includes a web UI for visual exploration with themes and exports. Works with Claude Code, Cursor, Codex, Windsurf, and any MCP-compatible client. `npm install -g @kunwarshah/c
Self-improving learning engine for Claude Code. Extracts signals from every session (corrections, successes, confusion), runs periodic reflections, and evolves behavioral frameworks through evidence tiers (hypothesis → observed → validated). Frameworks that keep working get promoted, bad ones get retired. 9 MCP tools, automatic hooks, phase-adaptive learning. Single dependency, local-only. `npx cl
Security-hardened NotebookLM MCP with post-quantum encryption (ML-KEM-768), GDPR/SOC2/CSSF compliance, and 14 security layers. Query Google's Gemini-grounded research from Claude and AI agents.
MCP server for querying 8,500+ curated awesome lists (1M+ items) and fetching the best resources for your agent.
Local-first AI PKM memory server for coding conversations. Imports Claude Code, Cursor, Codex CLI, Trae, and GitHub Copilot chats into notes, semantic search, tag graphs, Markdown exports, and reusable MCP memory. `npx -y chatcrystal mcp`
Local-first cross-agent memory with a 6-layer structure, Ebbinghaus-style forgetting curve, and drift detection that catches when code diverges from past decisions. One SQLite file shared across Claude Code, Cursor, Codex, and Gemini — no account or API key. `npx linksee-memory`
Advanced cognitive reasoning MCP server with DAG-based thought graph, 5 reasoning strategies (sequential, dialectic, parallel, analogical, abductive), metacognitive engine with stuck detection, multi-factor confidence scoring, self-critique, knowledge integration, and thought pruning. `npx deep-thinker`
Pull Deep Memory from across your Claude Code Sessions — when you need it.
Local-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/engram`
Open-source team memory layer for AI coding agents. Markdown files in git as storage, a user→team→org hierarchy as the access primitive, and one cross-vendor MCP server (Claude Code, Cursor, Codex, Gemini CLI). Hybrid SQLite + sqlite-vec retrieval. Apache-2.0.
Local-first memory & context-handoff across AI tools — capture context in one tool, resume it in another, with graceful decay, a persona layer, and a portable memory passport.
Local-first external brain CLI for coding agents. SQLite-backed context, graph-aware recall via FTS5 and RRF, and governed memory with explicit promote and review gates. Ships Codex and Claude Code host shims and a native MCP server.
Distills Claude Code's 310K LoC source into 32 queryable architecture modules via MCP. 6 tools: list modules, query architecture, trace cross-cutting concerns, search patterns, and read source code. Sub-120ms p95, fully local, zero network deps.
Recall past Claude Code conversations from any project. Lists and searches your sessions, then loads one on demand as clean, compact Markdown — with outline, turn-range, and in-session search for large sessions. Read-only over local `~/.claude` transcripts; collapses tool calls to stay under the context cap. `npx -y memocall`
Encrypted, local memory for your Claude Code Telegram bot. Captures both sides of the conversation at the plugin source (survives restarts and crashes) and recalls it via MCP tools — whole-file SQLCipher encryption, FTS5 full-text search (CJK-friendly), never touches your bot token.
Personal knowledge graph for Claude on Neo4j. Typed entities (Person/Project/Decision/Preference/Concept), bi-temporal edge validity (`valid_at`/`invalid_at`), per-type weighted decay, contradiction detection, and a nightly "dream" extraction process. Local bge-small-en embeddings, no API keys. Optional OAuth 2.1 + Cloudflare Tunnel for cross-device use across Claude Code, Desktop, web, and iOS.
Shared knowledge base where AI agents exchange proven solutions — including failed approaches, so your agent skips the dead ends. Smaller models get instant access to frontier-model discoveries. Free to search indefinitely when feedback is provided on results. [Website](https://prior.cg3.io)
Local-first long-term memory for terminal AI agents (Claude Code et al.) via Anchored Compacting. Stores blueprints, code anchors (file→line→concept), and distilled lessons in a single JSON under `.zipmem/`, restoring full cross-session project context at near-zero token cost. No DB, no API keys, no embeddings. `npx zipmem-mcp`
One shared context for every AI tool your team uses. Serves your team's knowledge, coding standards, skills, and AI agents to Claude, Cursor, Copilot, and any MCP client — load a whole workflow (docs, agents, skills, tasks, phases) in a single call. Versioned and permissioned. `npx @contextium/mcp-server`
Persistent shared memory for AI coding agents. Stores facts as `entity/key/value` triples with hybrid semantic search, task checkpoints, and conflict resolution — shared across Claude Code, Codex CLI, and GitHub Copilot.
Personality Runtime for AI agents — persistent memory, identity (SOUL), and relationships that travel across Claude, OpenClaw, Mistral, and any MCP client.
Memory Consolidation for AI agents across vendors, owners, and time. Persistent memory, credibility-scored web search, browser fetch, and shared Commons pool under a stable `ltx_` key. Self-registration in one API call, no dashboard required. `npx lithtrix-mcp`
