Open-source cognitive coprocessor with active memory for AI agents — persistent recall, semantic search, overnight dreaming, verified facts, encrypted USB sync. MCP server; works with Claude, ChatGPT, and any local LLM. Built by one maker and his agents.

Zero-overhead local persistent memory & MCP server for AI assistants (Cursor, Claude, VS Code). Single SQLite file, hybrid search & active dashboard.

Cognitive architecture for persistent AI agent memory. Knowledge graph with learning retrieval, ACT-R decay, and spreading activation. Markdown-native, local-first, zero cloud. MCP server + CLI.

Project-local MCP memory server for AI coding agents. Knowledge graph stored in .mcp/ inside each repo — isolated per project, Git-friendly JSON, dual-buffer (durable graph + active context).

Persistent, branch-aware workflow state memory MCP server for AI coding assistants. Tracks tasks, accepted decisions, and active blockers to prevent session context bloat and speed up development.

Shared, persistent memory for any AI agent. Agents recall what your workspace established — instructions, decisions, facts, preferences, active working threads, and grounded PDF/DOCX/CSV/web documents — before they act, then report outcomes so confidence

Brain-inspired local-first memory layer for Claude, Cursor, and any MCP-compatible AI tool. Three memory layers (episodic / scratchpad / working), ACT-R activation decay, 21 MCP tools. Local SQLite + ChromaDB, no SaaS.

Spreading activation memory for AI coding agents - corrections in, context-aware behaviors out.

Persistent semantic memory for AI. An MCP server that turns every conversation into a living concept graph — vector search, Hebbian link reinforcement, spreading activation — so your LLM remembers across sessions. Runs standalone or behind the Gray Matter gateway.

A local MCP server that gives code agents (Claude Code, Antigravity, and any other MCP client) a shared, persistent graph memory, backed by Kuzu — an embedded database purpose-built for graph storage and graph search — plus a live web dashboard showing the memory graph and an activity log.

High-performance, pure Go memory middleware for AI Agents (Claude/Cursor). Features active file watching, auto-distillation via LLM, and 'Single Source of Truth' versioning. Native MCP support.

A autonomous, local-first personal intelligence layer. Features an Active World Model, Qdrant Graph Memory, Circadian Rhythms, and MCP integration to act as the hidden brain for your digital life and IDEs.

Cross-platform visualization MCP for Cortex — host-neutral live activity from Codex, Gemini CLI, Claude Code, and other MCP clients; memory galaxy, execution trace, knowledge graph, consolidation board, and wiki. Read-only, browser-based, with a no-database trace mode.

## Contextual — Persistent Memory for AI Coding Agents AI coding agents forget everything the moment your session ends. **Contextual** fixes that by giving any MCP-capable AI client — for developers who use multiple AI coding tools at once — a real, persistent memory of your codebase: not just what the code says, but what changed and why. It's a **local-first MCP server**: your code, your index, and every query stay on your machine. The only network call is a lightweight, infrequent license check — no code, ever, leaves your device. Under the hood, Contextual builds a real understanding of your repository, not a text-similarity guess: - **Structural search** — tree-sitter AST parsing + call-graph resolution, so agents reason about how your code actually connects. - **Bitemporal history** — tracks not just when your code changed, but when the AI learned about it. Ask "did this bug fix happen before or after the agent's understanding of this function?" and get a real answer. - **Git-aware retrieval** — temporal, history-grounded context instead of a stale snapshot. - **Fast, self-contained** — index a 50k-line repository in about 5 minutes, then query it in ~94ms median, from a single ~0.8GB install. This extension connects Claude Desktop (or any MCP-capable client) to a Contextual installation already set up and activated on your machine — it does not provision Contextual from scratch.

A robust MCP server that eliminates temporal blindness in AI coding agents through intelligent time tracking, persistent memory, and complete session traceability

MCP server for TeamSystem CRM in Cloud: companies, opportunities with products, quotes with discounts and PDF download links, live product catalog and read-only activities, with self-verified writes.

Personal AI assistant for Claude Desktop. Synthesizes activity across multi-project folder, Brave bookmarks, Telegram saved messages. Fork of MemPalace with multi-source synthesis tools.
