> willow-mcp — willow-memory-willow-mcp. Use this tool when you need to manage agent interactions with a secure and persistent memory system, solving problems of access control and task queue management. It takes in standard input/output (stdio) from MCP clients and outputs controlled access to tasks and memory, utilizing manifest-based ACL and a Postgres knowledge base. Ideal for use cases requiring sandboxed task execution and persistent data storage, such as git-based workflows.
