Why it matters

sagashield targets the emerging need to add transactional safety and guardrails to autonomous AI agents and MCP-based tool calling, a layer defenders must evaluate as agentic systems gain real-world action capabilities.

sagashield is an open-source project (v0.3.0) providing an ACID transactional Saga runtime, a 'Step-0' security guardrail, and an MCP server for autonomous AI agents, published on GitHub with evals, fuzzing harnesses, examples, and a Python SDK.
