List all services for a specific provider
AI agents call get_provider_services to retrieve information from OpenAPI Directory 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 and lists metadata about services available from a provider in the OpenAPI Directory. It performs a simple data query with no capability to modify, delete, execute code, or commit financial transactions. The blast radius of misuse is minimal — an agent could only access informational content already published in a public API directory.
From the tool's definition Tool name is 'get_provider_services' and description states 'List all services for a specific provider' — uses the verb 'List', which is a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_provider_services gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OpenAPI Directory MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_provider_services:
{
"version": "1",
"default": "deny",
"tools": {
"get_provider_services": {}
}
}get_provider_services is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all services for a specific provider. It is categorised as a Read tool in the OpenAPI Directory MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OpenAPI Directory MCP Server MCP server in PolicyLayer and add a rule for get_provider_services: 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 OpenAPI Directory MCP Server. Nothing to install.
get_provider_services 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_provider_services 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_provider_services. 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_provider_services is provided by the OpenAPI Directory MCP Server MCP server (rawveg/openapi-directory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OpenAPI Directory MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
