Mandare MCP

An open-source control and accountability layer for AI agent fleets that provides signed identities, spending limits, and a tamper-evident ledger. It allows operators to verify agent actions, enforce budgets, and execute kill switches for runaway agents, ensuring local-first, non-custodial security.
