Brainfeather

Long-term memory for AI coding agents. Brainfeather records durable project facts (stack, decisions, conventions) once and recalls them in every MCP client, so Claude Code, Cursor, OpenCode and others start each session with the same context. - **get_context** loads what is already on record before the agent writes code - **search_memory** looks up past decisions before choosing a library or pattern - **save_memory** stores facts the user stated or confirmed - **capture_activity** queues inferred facts for review; nothing enters recall until approved - **list_entities** and **traverse_graph** explore the project's tools, languages and concepts Memory is scoped per project. Requires a Brainfeather API key from https://brainfeather.com/api-keys. Guide: https://brainfeather.com/ai-agent-memory
