list_apis
AI agents call list_apis to retrieve information from API Status Check MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to return a list of available APIs without modifying or executing anything. While the description is empty, the name 'list_apis' and the context of sibling read-only status-checking tools strongly indicate this is a simple data retrieval operation. Confidence is reduced slightly due to the missing description, but the surrounding context makes the intent clear.
From the tool's definition Tool named 'list_apis' with no description; sibling tools include 'check_status', 'check_url', and 'list_categories', all of which are query/lookup operations.

list_apis. It is categorised as a Read tool in the API Status Check MCP Server MCP Server, which means it retrieves data without modifying state.
Register the API Status Check MCP Server 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 API Status Check MCP Server. 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 API Status Check MCP Server MCP server (shibley/apistatuscheck-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
