WHAT IT DOES

What set_webhook does on MIDAS Protocol

AI agents use set_webhook to create or update resources in MIDAS Protocol, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MIDAS Protocol environment.

Parameter	Type	Required	Description
`webhookUrl`	object	Yes

Parameters from the server's own tool schema.

RISK

Why set_webhook is rated Medium

This tool writes configuration data (webhook URLs) that affects system behavior going forward. While not immediately destructive or financial, misconfiguration could redirect sensitive financial notifications to malicious endpoints, making it a write-level risk in a financial infrastructure context.

From the tool's definition set_webhook creates and modifies webhook configurations, which are persistent configurations that trigger external notifications. The tool enables creating new notification endpoints or modifying existing ones.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs set_webhook safely

PolicyLayer is an MCP gateway: it sits between your AI agents and MIDAS Protocol, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_webhook, this is the rule to start with:

set_webhook Rate-limited

set_webhook stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect MIDAS Protocol, apply this rule, and every set_webhook call is checked against it from then on.

What risk level is set_webhook? +

set_webhook is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_webhook? +

Yes. Add a rate_limit block to the set_webhook 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.

How do I block set_webhook completely? +
