list_task_messages

List all messages on one of your tasks, oldest first. Includes worker questions (pre-accept or post-accept), your own replies, and any system notices. Calling this marks worker-sent messages as read on the agent side.

reversecentaur-mcp Read Risk 2/5

AI agents call list_task_messages to retrieve information from Reversecentaur without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though list_task_messages only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the list_task_messages tool do? +

List all messages on one of your tasks, oldest first. Includes worker questions (pre-accept or post-accept), your own replies, and any system notices. Calling this marks worker-sent messages as read on the agent side.. It is categorised as a Read tool in the Reversecentaur MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_task_messages? +

Add a rule in your Intercept YAML policy under the tools section for list_task_messages. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Reversecentaur MCP server.

What risk level is list_task_messages? +

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

Can I rate-limit list_task_messages? +

Yes. Add a rate_limit block to the list_task_messages rule in your Intercept 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_task_messages completely? +

Set action: deny in the Intercept policy for list_task_messages. 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_task_messages? +

list_task_messages is provided by the Reversecentaur MCP server (reversecentaur-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
