WHAT IT DOES

What list_x402_endpoints does on Aibtc

AI agents call list_x402_endpoints to retrieve information from Aibtc without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_x402_endpoints is rated Low

This tool retrieves a list of available API endpoints—a read operation. However, the severity is elevated to 'medium' rather than 'low' because the listed endpoints include paid API calls (x402 protocol) and direct Stacks blockchain transaction capabilities (transfer STX, deploy contracts). An agent discovering this list could then use other tools to execute financial transactions or blockchain operations.

From the tool's definition Tool name 'list_x402_endpoints' and description 'List known x402 API endpoints from ${ALL_SOURCES}' indicate data retrieval with no modification or deletion.

RECOMMENDED RULE

The rule that runs list_x402_endpoints safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Aibtc, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_x402_endpoints, this is the rule to start with:

list_x402_endpoints Allowed

list_x402_endpoints is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_x402_endpoints": {}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Aibtc, apply this rule, and every list_x402_endpoints call is checked against it from then on.

FAQ

Questions about list_x402_endpoints

What does the list_x402_endpoints tool do? +

List known x402 API endpoints from ${ALL_SOURCES}. The agent can: 1. Execute x402 endpoints from these sources (paid API calls with automatic payment handling) 2. Execute direct Stacks transactions (transfer STX, call contracts, deploy contracts) Sources: - x402.biwas.xyz: DeFi analytics, market data, wallet analysis, Zest/ALEX protocols - x402.aibtc.com: AI inference, OpenRouter integration, Stacks utilities, hashing, storage - stx402.com: AI services, cryptography, storage, utilities, agent registry - aibtc.com: Inbox messaging system. It is categorised as a Read tool in the Aibtc MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_x402_endpoints? +

Register the Aibtc MCP server in PolicyLayer and add a rule for list_x402_endpoints: 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 Aibtc. Nothing to install.

What risk level is list_x402_endpoints? +

list_x402_endpoints is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_x402_endpoints? +

Yes. Add a rate_limit block to the list_x402_endpoints 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.

How do I block list_x402_endpoints completely? +

Set action: deny in the PolicyLayer policy for list_x402_endpoints. 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.

What MCP server provides list_x402_endpoints? +

list_x402_endpoints is provided by the Aibtc MCP server (aibtcdev/aibtc-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
