CEL
Common Expression Language (CEL) is an open-source, lightweight expression language developed by Google, designed to evaluate expressions in a safe and controlled environment. CEL features deterministic execution, no side effects, high performance, type checking, and cross-language implementations. It is commonly used in access control policies, configuration validation, data filtering, and business rule engines, and is widely adopted in cloud-native projects such as Kubernetes and Envoy.
Core Facts
Timeline (last 90 days)
agentgateway has a built-in MCP authorization policy mcpAuthorization, which evaluates mcp.tool.name, mcp.tool.target, and JWT claims using CEL rules.
On agentgateway v1.5.0, the CEL evaluation result of every read_text_file call is exactly the same regardless of the path; tool-name rules work while path rules have no data to read.
