Declarative Policy Rule Definition Without Code

via “declarative policy definition and composition”

Core proxy engine for Cordon for MCP — the security gateway for MCP tool calls

Unique: Provides a declarative policy language tailored to MCP tool calls, allowing non-developers to define security rules without understanding the underlying proxy architecture

vs others: Offers MCP-specific policy syntax that understands tool call semantics (tool name, parameters, context), whereas generic API gateway policies require manual mapping of tool calls to API endpoints

via “policy rule definition and management”

Policy-based MCP tool call proxy

Unique: Provides a dedicated policy definition layer for MCP tool access control, separating policy logic from code and enabling non-developers to manage tool access rules through declarative configuration

vs others: Offers MCP-specific policy language and management, whereas generic policy engines (e.g., OPA) require additional integration work and lack MCP protocol semantics

via “declarative policy rule evaluation engine”

Policy-as-code enforcement for MCP tool calls

Unique: Implements a dedicated rule evaluation engine for MCP tool calls rather than relying on generic policy frameworks, allowing optimization for tool-specific patterns like argument validation and schema-aware matching

vs others: More specialized for tool call governance than generic policy engines (e.g., OPA), with native understanding of MCP tool schemas and arguments, though less flexible for non-tool-related policies

Unique: Provides a no-code rule definition interface that abstracts linter plugin development, allowing non-engineers to create and maintain custom rules without touching code or build systems — most traditional linters require custom plugin development or regex-based configuration

vs others: Eliminates the need for custom linter plugin development that tools like ESLint, Pylint, or Checkstyle require, reducing time-to-enforcement for organizational policies
