About

Operator by Planck Proof is an agentic API penetration testing tool. Give it your OpenAPI spec and credentials for two or more roles; it tests every operation across roles and tenants for authorization flaws (BOLA, BFLA, BOPLA), broken authentication, injection, mass assignment and business-logic abuse, chaining findings into attack paths. Coverage maps to the OWASP API Security Top 10 and includes REST, GraphQL and gRPC APIs, plus the APIs behind AI agents, LLM apps and MCP servers. Every finding ships with the exact request and response, a CVSS score and a runnable proof-of-concept your engineers can execute to confirm the issue and verify the fix. Scope, rate and data controls keep runs safe against real environments, and you can steer or pause the agent at any time. Run it on every deploy, retest fixes, and send findings to Jira. Reports are built for engineers and auditors (SOC 2, PCI DSS, HIPAA). First scan is free; Pro and Enterprise are quoted per API by endpoint volume.

About

Specmatic offers a no-code, specification-driven, visual approach to API testing by leveraging API specifications to automatically execute positive and negative tests. Specmatic Studio offers broad format and protocol support across REST, SOAP, GraphQL, gRPC, WebSockets, and asynchronous messaging systems (message queues and event-driven APIs). The platform provides a comprehensive toolkit for API development and testing, utilizing specs as the single source of truth. Key features include: • Contract testing across various protocols • Service virtualization and mocking • Workflow and resiliency testing • Backward compatibility checks to prevent breaking changes • Open-source testing tools for OpenAPI, MCP and SOAP • Postman collection import for spec creation Specmatic focuses on functional correctness, contract compliance, resiliency, and compatibility testing. Genie assists API design, enabling interactive validation of the API spec prior to generating an MCP server.
