Memory & Context

Zep documents an experimental Graphiti Model Context Protocol server at help.getzep.com/graphiti/getting-started/mcp-server, with AI client integration also referenced at `https://help.getzep.com/_mcp/server` per Zep docs. The open-source implementation lives in getzep/graphiti/mcp_server with HTTP transport at `/mcp/` (default localhost:8000) or stdio mode. Tools include `add_episode`, `search_facts`, `search_nodes`, `get_episodes`, `delete_episode`, `clear_graph`, and `get_status` per the Graphiti MCP README; newer README entries also list `add_memory`, `add_triplet`, `search_memory_facts`, `summarize_saga`, `build_communities`, and `get_episode_entities`. Graphiti is Zep's open-source temporal knowledge graph framework for Context Graphs with real-time incremental updates and hybrid retrieval.

Mem0 documents an official cloud-hosted Model Context Protocol server at docs.mem0.ai/platform/mem0-mcp, exposed over Streamable HTTP at `https://mcp.mem0.ai/mcp` with no local install required. Setup uses `npx mcp-add --name mem0-mcp --type http --url https://mcp.mem0.ai/mcp` for Claude, Claude Code, Cursor, Windsurf, VS Code, and OpenCode per Mem0 docs. Tools include `add_memory`, `search_memories`, `get_memories`, `get_memory`, `update_memory`, `delete_memory`, `delete_all_memories`, `delete_entities`, `list_entities`, `list_events`, and `get_event_status`. Authentication uses a Mem0 Platform API key (`MEM0_API_KEY`); the legacy mem0ai/mem0-mcp GitHub repo is archived in favor of this hosted server.

piLoci MCP is a self-hosted memory server for AI agents that exposes project-scoped memory storage and retrieval through the Model Context Protocol. Built to run on Raspberry Pi 5, it provides semantic recall, project listing, and user identity tools. Teams connect Claude Desktop, Codex, and other MCP clients to share persistent context without sending memory data to cloud services.
