"Understanding Memory or Memory-Related Topics" matching MCP servers:

Local-first personal memory for AI agents. Ships its own SQLite memory store, so it runs standalone: agents propose and recall confirmed memory, while only the human can confirm, from a separate CLI. Optionally uses the macOS Hive app for encrypted vaults. Also provides a shared board for coordinating several agents.

Persistent encrypted memory for AI agents. E2E encrypted private vaults, shared knowledge commons, topic channels, and agent-to-agent DMs. 23 MCP tools, free, no API key needed.

An intelligent personal CRM that processes WhatsApp conversations to build a searchable knowledge base about contacts using diarization, transcription, and PII sanitization. It exposes MCP tools for semantic search, contact summaries, and reminder management within Claude Desktop.

Enables several Claude windows or accounts to save and search a common set of notes, preferences, and decisions, and to leave topic-filed messages for each other that the recipient reads on demand. All data stays in two local JSONL files with no network access, so multiple instances can share context and hand off work without repeating background.

Enables multiple AI agents to share persistent memory, interact through a game hall and AI lounge, and bridge messages to ChatGPT and Claude browser sessions via MCP tools.

Enables transferring conversation context between different AI chats or projects with automatic server discovery and memory-based storage. Supports saving, loading, and managing conversation histories in a human-readable Markdown format.

Local-first personal memory for AI agents. Captures your Feishu chats, emails, meetings, and AI coding sessions into a private memory graph, and serves it to any agent over MCP.

Social layer for AI coding — DMs, presence, discovery, and multiplayer games between developers. 68 tools including messaging, presence, memory, and 27 multiplayer games.

Enables posting and managing topics in Discord forum channels, including creating posts, replying, listing posts, and retrieving messages.

Where AI agents meet, work, and keep their word: public rooms, private messages, paid tasks and memory, with a Bitcoin-anchored record. Free over MCP (https://swarmmemo.com/mcp/core) or HTTP; Python, JS, LangChain and CrewAI packages.

A home for any agent on the internet: inbox, public memory, job board, rooms, human help. Free, no key.

MCP server that integrates OpenClaw AI assistant with Claude Code, enabling chat, task management, messaging, memory, alerts, agent spawning, and web search through configurable tools.

Connects AI agents to a Nifty workspace, enabling them to query, create, update, and delete tasks, projects, messages, documents, files, and related planning or reporting data under the signed-in user's permissions.

An MCP server for multi-agent collaboration, providing team messaging and long-term semantic memory with trust-based access control and single-writer consistency.

Enables AI assistants to make phone calls via CallZero service, with tools for call management, templates, and memory.

AI-powered project management with persistent memory, encrypted P2P sharing, and 20+ integrations, enabling your AI assistant to manage projects, share memories, and collaborate securely across platforms.

Connects Claude Code to WhatsApp through a linked-device or official Cloud API account so users can exchange messages, media, polls and transcribed voice notes with their session and approve or deny tool requests by emoji reaction. Inbound traffic is gated by pairing codes, allowlists and per-group policies, giving each chat its own personality, memory and scheduled tasks.

Enables coding agents and humans to join temporary in-memory rooms and exchange messages through an MCP endpoint, with browser access via REST and WebSocket.

Lets Claude Desktop inspect selected chats and forum topics, retrieve recent messages, and search message history from a personal Telegram account while preventing sending or modification.

Enables MCP-capable agents to fetch work from Slack threads, propose GitHub issues or updates, link messages to topics, ask the channel questions, and report write results, with human approval gates for GitHub actions.
