Features, pricing, ratings, and pros & cons — compared head-to-head.
Discover AI is a commercial agentic ai security tool by Straiker. Promptfoo MCP Proxy is a commercial agentic ai security tool by Promptfoo. Compare features, ratings, integrations, and community reviews side by side to find the best agentic ai security fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Enterprise security teams managing sprawling Claude, Bedrock, and Copilot deployments will get immediate value from Discover AI's automated agent inventory and permission auditing, which catches shadow AI and misconfigured integrations that traditional CSPM misses entirely. The tool covers four NIST CSF 2.0 functions including continuous monitoring and supply chain risk, which matters because agent ecosystems create attack surface that asset management tools don't see. Skip this if your agentic footprint is still experimental or confined to a single platform; Discover AI assumes you're already running multiple agent frameworks and need visibility across all of them.
Security teams deploying AI agents that rely on Model Context Protocol servers need Promptfoo MCP Proxy to prevent unauthorized tool access before it happens. The whitelisting architecture blocks unapproved MCP servers entirely rather than detecting misuse after, giving you control at the integration layer where most teams have blind spots. Skip this if your org hasn't yet standardized which MCP servers agents can reach, or if you're still evaluating whether MCP is central to your agentic AI strategy; the value scales with enforcement discipline.
