Runtime security for AI agents
See what your agents do. Decide what they can.
Fendray is a policy enforcement gateway for AI agent tool calls. Real-time verdicts across LangChain, MCP, and raw provider APIs — sub-20ms, framework-agnostic.
The visibility gap
Enterprise AI agents are taking actions on behalf of your business — querying databases, calling APIs, moving money, sending email. Each of those actions is a tool call. Each tool call is a security event.
Most teams can see what their models say. Very few can see, govern, or audit what their agents do.
Per-provider guardrails don't help when you're running across LangChain, MCP, internal frameworks, and three model providers. Policy ends up scattered across SDKs, prompt templates, and tribal knowledge. There's no enforcement layer that knows what an agent is allowed to invoke, under what conditions, on whose behalf.
What Fendray does
Inspect every tool call
Fendray sits on-path between agents and tools. Every invocation passes through — visible, logged, attributable.
Enforce policy in real time
Allow, block, redact, or escalate. Verdicts in under 20ms at p99. Policy lives as code, not in prompts.
Detect what providers miss
Prompt injection, PII leakage, geographic compliance violations, anomalous behavior — checked in parallel, across providers, in one place.
Human approval for high-risk actions
Route sensitive tool calls to a human reviewer before execution. Built for the actions that shouldn't be fully autonomous yet.
Drop-in, framework-agnostic
Fendray works as an MCP gateway and as an SDK shim for non-MCP frameworks. Point your agents at Fendray instead of directly at your tools and providers. No retraining, no prompt rewriting, no code changes to your agent logic.
- — MCP servers — proxy any MCP-compliant server through Fendray's gateway
- — Agent frameworks — LangChain, CrewAI, AutoGen, raw provider SDKs (Anthropic, OpenAI, Google)
- — Custom agents — direct integration via the Fendray SDK
We're recruiting design partners
Fendray is in the final stretch before MVP. We're opening five to eight design partner slots for teams running AI agents in production or staging, who feel the visibility gap firsthand and want to shape the runtime security layer they wish existed.
Design partners get free access through 2026, a direct line to the founding team, real influence over what ships, and locked-in pricing when we commercialize. In return, we ask for a real workload running through Fendray within 60 days, biweekly feedback, and permission to reference you publicly once you're comfortable.
