List brokered downstream MCP tasks.
AI agents call gateway.tasks_list to retrieve information from PMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists information about downstream MCP tasks without modifying, executing, or deleting anything. It is purely informational, making it a Read category tool with low severity since listing tasks poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'gateway.tasks_list' and description 'List brokered downstream MCP tasks' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access gateway.tasks_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for gateway.tasks_list:
{
"version": "1",
"default": "deny",
"tools": {
"gateway.tasks_list": {}
}
}gateway.tasks_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
List brokered downstream MCP tasks. It is categorised as a Read tool in the PMCP MCP Server, which means it retrieves data without modifying state.
Register the P MCP server in PolicyLayer and add a rule for gateway.tasks_list: 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 PMCP. Nothing to install.
gateway.tasks_list 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 gateway.tasks_list 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 gateway.tasks_list. 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.
gateway.tasks_list is provided by the P MCP server (viperjuice/pmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from PMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
