AI agents call get_task_list to retrieve information from MCP-A2A-Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Given the context of a gateway managing A2A agent communication and the naming pattern of sibling tools, 'get_task_list' most likely retrieves or queries task data without modifying state. No side effects are evident from the name. Confidence is moderate because the empty description limits certainty, but the tool name and server context strongly suggest a read operation.
From the tool's definition Tool name 'get_task_list' indicates retrieval of a list of tasks. Description is empty, but the naming convention aligns with read-only query operations (see sibling tools like 'get_task_result' and 'list_agents' which are clearly retrieval-focused).
Documented attack patterns abuse exactly the kind of access get_task_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP-A2A-Gateway, and nothing reaches the server without passing your rules. This is the rule we recommend for get_task_list:
{
"version": "1",
"default": "deny",
"tools": {
"get_task_list": {}
}
}get_task_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_task_list. It is categorised as a Read tool in the MCP-A2A-Gateway MCP Server, which means it retrieves data without modifying state.
Register the MCP-A2A-Gateway MCP server in PolicyLayer and add a rule for get_task_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 MCP-A2A-Gateway. Nothing to install.
get_task_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 get_task_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 get_task_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.
get_task_list is provided by the MCP-A2A-Gateway MCP server (yw0nam/mcp_a2a_gateway). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP-A2A-Gateway, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
