List all active tasks, optionally filtered by project ID, filter query, or label name.
AI agents call list_tasks to retrieve information from Todoist MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries task data without side effects. It performs a read-only operation that does not modify, delete, or execute any actions. The filtering parameters are all query-based and do not alter state. Severity is low because exposure of this tool poses minimal risk; at worst, an agent could retrieve unwanted task information, but cannot modify or delete anything.
From the tool's definition Tool name 'list_tasks' and description 'List all active tasks' indicate a retrieval operation. The description explicitly states filtering capabilities (by project ID, filter query, or label name) with no mention of creating, modifying, or deleting data.
Attacks that exploit this kind of access
List all active tasks, optionally filtered by project ID, filter query, or label name. It is categorised as a Read tool in the Todoist MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Todoist MCP Server MCP server in PolicyLayer and add a rule for list_tasks: 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 Todoist MCP Server. Nothing to install.
list_tasks 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 list_tasks 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 list_tasks. 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.
list_tasks is provided by the Todoist MCP Server MCP server (strangetoucane/mcp-todoist-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
