Simulate or handle the callback payload sent by Tunzaa to your webhook. Essential for grounding your webhook integration code with real payload examples.
AI agents invoke handle_callback to trigger actions in Tunzaa MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool triggers execution of webhook callback handling logic and can simulate or process real payment callback payloads from Tunzaa. It executes external-facing webhook operations whose effects depend on the payload arguments. While it may operate in mock mode by default, it can interact with live systems when credentials are provided, making it an Execute-category tool.

Attacks that exploit this kind of access
Simulate or handle the callback payload sent by Tunzaa to your webhook. Essential for grounding your webhook integration code with real payload examples. It is categorised as a Execute tool in the Tunzaa MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Tunzaa MCP Server MCP server in PolicyLayer and add a rule for handle_callback: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Tunzaa MCP Server. Nothing to install.
handle_callback is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the handle_callback rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for handle_callback. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
handle_callback is provided by the Tunzaa MCP Server MCP server (tunzaa/tunzaa_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
