PromptBrake launches free MCP server for prompt injection tests, OWASP mapping and agent tool-call checks
Specialist-Bee9801 · reddit · 2026-10-07
The creator of PromptBrake released a free remote MCP server (no account or API key needed) offering five AI-security testing tools: adversarial prompt injection payloads by attack category, OWASP LLM risk mapping, release-planning gap checks, response-text test packs, and new agent tool-call checks that assert which tools an agent must or must not call. One claude mcp add command connects it; tool-call packs can run in CI via a free GitHub Action against staging capture data. The MCP only prepares packs—it doesn't call your target or run tests.
