WHAT IT DOES

What submit_lead does on GateCore Marketplace

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

Parameter	Type	Required	Description
`lead`	object	Yes
`listing_id`	string	Yes

Parameters from the server's own tool schema.

RISK

Why submit_lead is rated Medium

An AI agent can call submit_lead faster than any human can review: one bad instruction and it creates or modifies resources in GateCore Marketplace by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs submit_lead safely

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

submit_lead Rate-limited

submit_lead 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.
