Run these free tools inside your AI agent

One read-only MCP server works with Claude, ChatGPT, Cursor, and other MCP clients. No PromptBrake account or API key required. Tool inputs and results are not stored; operational request metadata is logged. See our privacy policy.

Server URL https://promptbrake.com/free-tools/mcp

Claude

1. Open Settings → Connectors
2. Choose Add custom connector
3. Paste the server URL

ChatGPT

1. Open Settings → Connectors → Advanced and turn on Developer mode
2. Choose Create to add a connector
3. Paste the server URL and set authentication to None

Claude Code and Cursor

Claude Code, in your terminal:

claude mcp add --transport http promptbrake-free-tools https://promptbrake.com/free-tools/mcp

Cursor: add a remote MCP server with the same URL.

Then ask, for example: “Get the persona prompt injection payloads” or “Build a test pack for my refund chatbot.” Tools: prompt injection payloads, OWASP LLM mapper, ADLC release planner, and AI test case builder. Use them only on chatbots and APIs you own or are authorized to test.

Give your AI assistant a workflow for all four free tools

The PromptBrake skill guides your assistant through prompt-injection inputs, OWASP LLM risk mapping, AI release planning, and custom response test packs.

With Node.js installed, run this in your project and choose your supported assistant:

npx skills add AJ888/promptbrake-skills --skill promptbrake-free-tools

Connect the MCP server above separately. Your client must support both skills and remote MCP. The skill prepares test inputs and plans; running tests requires a configured PromptBrake runner and CI access. Text checks do not verify backend actions.
