List available API IDs grouped by category. Call first when unsure which apiId to use.
AI agents call listAllApis to retrieve information from Dynamic API Server (MCP) 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 information about available APIs without modifying, executing, or deleting anything. It serves a discovery purpose to help users identify which API to call next. The blast radius of misuse is minimal—an AI agent listing APIs cannot cause damage, though it gains information about what APIs exist.
From the tool's definition Tool name 'listAllApis' and description 'List available API IDs grouped by category' indicate a retrieval operation with no side effects. The verb 'list' is explicitly mentioned as a Read category example in the classification rules.
Attacks that exploit this kind of access
List available API IDs grouped by category. Call first when unsure which apiId to use. It is categorised as a Read tool in the Dynamic API Server (MCP) MCP Server, which means it retrieves data without modifying state.
Register the Dynamic API Server (MCP) MCP server in PolicyLayer and add a rule for listAllApis: 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 Dynamic API Server (MCP). Nothing to install.
listAllApis 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 listAllApis 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 listAllApis. 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.
listAllApis is provided by the Dynamic API Server (MCP) MCP server (1049861657/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
listAllApis is one line of Dynamic API Server (MCP)'s registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
