Get installer details for a specific app. Fetches information about the company, location, user, and installation details associated with the current OAuth token.
AI agents call list_marketplace_installations to retrieve information from GoHighLevel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a Read operation that queries and returns information about app installations and associated metadata. However, the severity is elevated from 'low' to 'medium' because the returned data includes company, location, and user information tied to an OAuth token, which could be sensitive organizational context that an AI agent might inadvertently expose or misuse in prompts/logs.
From the tool's definition Tool name includes 'list' and description states 'Fetches information about the company, location, user, and installation details' — retrieval of data with no modification or side effects.
Documented attack patterns abuse exactly the kind of access list_marketplace_installations gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and GoHighLevel MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_marketplace_installations:
{
"version": "1",
"default": "deny",
"tools": {
"list_marketplace_installations": {}
}
}list_marketplace_installations is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get installer details for a specific app. Fetches information about the company, location, user, and installation details associated with the current OAuth token. It is categorised as a Read tool in the GoHighLevel MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GoHighLevel MCP Server MCP server in PolicyLayer and add a rule for list_marketplace_installations: 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 GoHighLevel MCP Server. Nothing to install.
list_marketplace_installations is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_marketplace_installations 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 list_marketplace_installations. 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.
list_marketplace_installations is provided by the GoHighLevel MCP Server MCP server (busybee3333/go-high-level-mcp-2026-complete). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
