MCPWarden is a policy-checkable workflow runtime and guardrail layer for MCP tools. It imports MCP servers, requires explicit trust and effect metadata, plans approvals, blocks unsafe workflows, redacts sensitive outputs, and provides a plug-and-play CLI/local service for agent tooling.

Bounded workflow runtime for long-running agent execution with ledgered state, approvals, recovery, and progress updates.

Experimental open-source infrastructure for modular, auditable multi-agent orchestration.
