Spend fewer tokens. Remember more. Ship faster.

memtomem-stm is an MCP proxy that typically cuts token usage by 20–80% and gives your agent memory across sessions — with no changes to your upstream MCP servers.

It sits between your AI agent and its upstream MCP servers, compressing tool responses, caching repeated calls, and automatically surfacing relevant context from prior sessions via a memtomem LTM server.

What memtomem-stm does:

• Cuts token spend on repeated reads — compresses and caches tool responses, so the agent doesn't re-pay for the same file or search result. Works with Claude Code, Cursor, Claude Desktop, or any MCP client.
• Carries context across sessions — surfaces prior decisions from memtomem LTM automatically, so the agent picks up where it left off rather than re-discovering what it already knew.
• Drops in front of any MCP server — adds compression, caching, and observability as a proxy layer, without changes to upstream code.
