Assay MCP Firewall

Example Use Cases

• 1

  Control and audit tool calls securely.

• 2

  A deterministic and replayable policy enforcement layer.

• 3

  Integration with CI pipelines to catch regressions before production.

Description

Assay acts as a security layer between your MCP agent and its tools, intercepting and enforcing policies on tool calls such as read_file, exec, and web_search. It produces a deterministic, auditable, and cryptographically verifiable evidence trail for every decision, enabling compliance and security auditing without requiring a hosted backend or API keys. Assay supports multiple agent protocols through adapters and integrates easily into CI pipelines to block policy violations before production.
