taskwarrior_list
AI agents call taskwarrior_list to retrieve information from Taskwarrior MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to query/retrieve task information from Taskwarrior without modifying, deleting, or executing external operations. Despite the empty description, the name and context of the server make the intent clear. This has minimal security impact as a read-only operation.
From the tool's definition Tool name 'taskwarrior_list' and server description indicating it 'allows users to list, create, modify, and organize tasks' confirms this retrieves task data. The verb 'list' is explicitly enumerated as a Read operation in the classification rules.

Register the Taskwarrior MCP Server MCP server in PolicyLayer and add a rule for taskwarrior_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 Taskwarrior MCP Server. Nothing to install.
taskwarrior_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 taskwarrior_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 taskwarrior_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.
