PromptBrake Free Tools
Claude connectorCommunityFree AI test helpers: injection inputs, OWASP mapping, release plans, response checks and agent tool-call test packs.
Prepare tests and release plans for your own chatbot, agent or LLM API from Claude. Five free MCP tools provide prompt-injection inputs, OWASP LLM risk mappings, release planning, response-text test packs and agent tool-call test packs.
The MCP prepares artifacts; it does not contact your target or execute tests. Response checks compare text. Tool-call packs run with PromptBrake Action v0.2.0 after one-time staging application dispatcher capture, checking forbidden invocations and required typed arguments. Missing or incomplete capture cannot pass. Captured calls do not prove successful backend effects or replace tool permission enforcement. Licensed local runners add retained evidence and release gates.
No PromptBrake account or API key is required to use these MCP tools. Tool inputs/results are not stored; operational request metadata is logged. Use synthetic data and only test systems you own or are authorized to test. Setup: https://promptbrake.com/free-tools/agent-tool-call-checks
