L7 Guardrails — MCP, A2A & the wire

Inline inspection and enforcement on every agent interaction — Model Context Protocol (MCP) tool calls, Agent-to-Agent (A2A) messages, SQL, and LLM traffic — as it happens.

  • LLM traffic governance — Inspect and control what agents send to and receive from the model, per policy.
  • Prompt-injection defense — Detect and block malicious instructions hidden in prompts, documents and tool outputs.
  • Sensitive-data masking — Redact PII, secrets and credentials in requests and responses before they leave.
  • Database (SQL) firewall — Destructive or data-exfiltrating queries refused in-line, before the database runs them.
  • MCP tool-call governance — Parse Model Context Protocol (MCP) traffic and control which tools, methods and arguments each agent may invoke — and govern every MCP server as a first-class workload.
  • A2A cross-agent control — Inspect Agent-to-Agent (A2A) messages and govern which agents may call which, with what payloads.
  • Identity-aware egress — Every outbound call checked against verified identity and an allowlist — nowhere to send data.
  • Secrets & credential protection — Broker access to credentials so static tokens can't be harvested or leaked.
  • Sensitive-path blocklist — SSH keys, cloud credentials and cluster configs are off-limits by default.
  • Runaway & loop containment — Catch agents stuck in loops or blowing past budget, and stop them.
  • Encrypted-traffic inspection — Inspect encrypted egress transparently, with no application change.
