Retrieve a list of companies/customers with advanced filtering options
AI agents call get_companies to retrieve information from HUDU MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries company/customer data without creating, modifying, deleting, or executing any actions. It is a straightforward Read operation. The filtering options are query parameters that do not alter underlying data. Severity is low because unauthorized access to a company list poses minimal direct harm compared to credentials, passwords, or financial data that may be stored in the same system.
From the tool's definition Tool name 'get_companies' and description 'Retrieve a list of companies/customers' directly indicate a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_companies gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and HUDU MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_companies:
{
"version": "1",
"default": "deny",
"tools": {
"get_companies": {}
}
}get_companies is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve a list of companies/customers with advanced filtering options. It is categorised as a Read tool in the HUDU MCP Server MCP Server, which means it retrieves data without modifying state.
Register the HUDU MCP Server MCP server in PolicyLayer and add a rule for get_companies: 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 HUDU MCP Server. Nothing to install.
get_companies 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 get_companies 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 get_companies. 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.
get_companies is provided by the HUDU MCP Server MCP server (jlbyh2o/hudu-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from HUDU MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
