List all loaded APIs with basic info
AI agents call list_apis to retrieve information from OpenAPI Search 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 displays metadata about loaded APIs without creating, modifying, deleting, or executing any operations. It is a pure information retrieval function with minimal security risk and no side effects.
From the tool's definition Tool name 'list_apis' combined with description 'List all loaded APIs with basic info' indicates a query/retrieval operation with no modification or execution capabilities.
Attacks that exploit this kind of access
List all loaded APIs with basic info. It is categorised as a Read tool in the OpenAPI Search MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OpenAPI Search 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 OpenAPI Search 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 OpenAPI Search MCP Server MCP server (sheepion/openapi-search-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
