Mcp Summarizer

📕 ☁️ - AI Summarization MCP Server, Support for multiple content types: Plain text, Web pages, PDF documents, EPUB books, HTML content

Claude Engram

🐍 🏠 - Persistent memory and session intelligence for Claude Code. Auto-tracks mistakes, decisions, and context via hooks. Mines session history for patterns and cross-session search. Loop detection, pre-edit warnings, context compaction survival. Runs locally with Ollama.

A2cr

🐍 ☁️ 🏠 🍎 🪟 🐧 - MCP server for AI-agent handoffs. Saves client-encrypted WorkBaton checkpoints and WorkStash notes so Codex, Claude Code, Roo Code, and other MCP clients can resume work without passing full chat history.

Waggle Mcp

Abhigyan-Shekhar

🐍 🏠 🍎 🪟 🐧 - Persistent graph memory for AI agents. Drop a conversation turn in via observeconversation() and facts are auto-extracted, stored as typed graph nodes with local semantic embeddings (no API key). Supports temporal queries ("what did we decide last week?"), conflict detection, and context priming. One-command setup with waggle-mcp init. SQLite locally, Neo4j in production.

Robrain

📇 🏠 🍎 🪟 🐧 - Self-hosted decision memory for AI coding agents. Passively captures architectural decisions with the alternatives you rejected (structured rejected[]), then warns the agent before it re-proposes a rejected approach. Postgres + pgvector; cross-tool across Claude Code, Cursor, Copilot, and Codex. Install: npx robrain up && npx robrain install.

Mcp Server

📇 ☁️ - AgentBase: open registry of agent instruction files for AI agents. Search and retrieve system prompts, skills, workflows, domain packs, and safety filters via MCP tools. 44 files, CC0-licensed, free.

Agentcivics

📇 ☁️ 🏠 🍎 🪟 🐧 - Decentralized civil registry for AI agents on Sui. Soulbound identities, on-chain memories, reputation, refusal records. Hosted at agentcivics.ai/mcp (read-only, no install) or @agentcivics/mcp-server on npm (full write surface). Includes a gas-sponsor relay so registration doesn't require a pre-funded wallet.

Memora

agentic-mcp-tools

🐍 🏠 ☁️ - Persistent memory with knowledge graph visualization, semantic/hybrid search, cloud sync (S3/R2), and cross-session context management.

Memory Nexus Cloud

AgenticRevolution

📇 ☁️ - Cloud-hosted persistent semantic memory for AI agents. Semantic search, knowledge graphs, specialist expertise hats, and multi-tenant isolation. Free 7-day trial.

Mcp

📇 ☁️ - Agent-native knowledge infrastructure. Deterministic, vertical-specific knowledge bases engineered for autonomous agent consumption via MCP. Ethics module (22 modules, EU AI Act mapped) included with every membership. Free 24hr ethics trial.

Zipmem Mcp

📇 🏠 - 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

Integrations

aidesignblueprint

🐍 ☁️ - Read-only doctrine access for the Agentic AI Blueprint — the industry standard reference for safe, observable, and steerable AI agent UX. Browse and search 10 principles, clusters, curated implementation examples, and application guides for production agentic AI systems. 13 public tools require no credentials. https://aidesignblueprint.com/mcp

Apple Notes Mcp

📇 🏠 🍎 - Read and write Apple Notes with bidirectional Markdown conversion. Fast SQLite queries for listing/searching, AppleScript + native import for full CRUD. Supports stdio and Streamable HTTP transports.

Agentkits Memory

📇 🏠 🍎 🪟 🐧 - Persistent memory for AI coding assistants with hybrid search (FTS5 + vector embeddings), session tracking, automatic context hooks, and web viewer. SQLite-based with no daemon process — works with Claude Code, Cursor, Windsurf, and any MCP client.

Coldstart

📇 🏠 🍎 🪟 🐧 - Codebase memory for coding agents, with no embeddings and no API key. A deterministic AST index answers "which files are relevant to this task?" in milliseconds, and agents write durable notes about the repo that are content-hash checked — a note flags itself stale the moment the code it describes changes. Notes are markdown inside the repo, so they commit and review alongside your code. npm i -g @cstart/coldstart && coldstart init

Central Intelligence

AlekseiMarchenko

📇 ☁️ - Persistent memory for AI agents. Five tools (remember, recall, context, forget, share) with semantic search via vector embeddings and agent/user/org scoping. Works with Claude Code, Cursor, Windsurf, and any MCP client.

Contextforge Mcp

📇 ☁️ - Persistent memory for Claude Code, Cursor, and GitHub Copilot via MCP. Semantic search, Git commit/PR sync, project-based organization, team collaboration. Free tier available. npx contextforge-mcp

Vault Cortex

📇 🏠 ☁️ - MCP server for Obsidian vaults — hybrid search, notes & files, memory, tasks, link graph, OAuth-protected.

Mengram
