Koskamo

1Claw Vault MCP

An MCP server that provides AI agents with secure, just-in-time access to secrets stored in HSM-backed vaults. It supports tools for secrets retrieval, multi-chain transaction signing, execution bindings, memory, and automations. The server handles JWT exchange and refresh, ensuring credentials are fetched at call time and not cached in the model's context.
