Kaeru MCP Server

Name: Kaeru MCP Server
Author: lamantinai

Memory for LLM agents: a local graph where the agent itself keeps decisions, tasks, hypotheses and reasoning between sessions, and gets a summary of what is open and overdue on every return to a project. Single Rust binary with no embedding model or LLM calls inside; one daemon serves several agents at once, with an optional self-hosted cloud for teams. Works with Claude Code, Codex, Cursor, opencode and any MCP client.
