List all available API specifications with their metadata
AI agents call list_apis to retrieve information from Sufetch without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns metadata about available APIs without side effects. It is a straightforward read operation that retrieves and presents information, matching the 'Read' category definition of retrieving or querying data with no side effects. The low severity reflects that listing available APIs poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'list_apis' and description 'List all available API specifications with their metadata' indicate retrieval of information without modification or execution of external operations.
Documented attack patterns abuse exactly the kind of access list_apis gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sufetch, and nothing reaches the server without passing your rules. This is the rule we recommend for list_apis:
{
"version": "1",
"default": "deny",
"tools": {
"list_apis": {}
}
}list_apis is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all available API specifications with their metadata. It is categorised as a Read tool in the Sufetch MCP Server, which means it retrieves data without modifying state.
Register the Sufetch MCP server in PolicyLayer and add a rule for list_apis: 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 Sufetch. Nothing to install.
list_apis 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_apis 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_apis. 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_apis is provided by the Sufetch MCP server (productdevbook/sufetch). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Sufetch, 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.
