Memdata
Gives Claude persistent memory across conversations through MemData's vector storage API. You get semantic query, ingest with auto-chunking and embedding, and session management that preserves context between restarts. The session_start tool surfaces what you were working on last time, while session_end saves handoff notes for next run. Built for both human-managed API keys and autonomous agents via x402 wallet payments on Base, where your wallet address becomes your identity. Useful when you need an AI to remember project decisions, meeting notes, or accumulated context without re-explaining everything each session. Handles text and markdown through MCP, PDFs and audio through the dashboard.

memdata-mcp
MCP server for MemData - persistent memory for AI agents.
Give Claude, Cursor, or any MCP-compatible AI long-term memory across conversations.
What it does: Store notes, decisions, and context → retrieve them semantically later. Your AI remembers everything.
🚀 New in v1.7.0: Autonomous Agent Support
Agents can now pay for themselves. No API key. No human in the loop.
Using the x402 payment protocol, autonomous agents can use their wallet to pay per request with USDC on Base. Your wallet address IS your identity - same wallet, same memories across sessions.
Why MemData?
AI assistants forget everything between sessions. MemData fixes that:
