List completed tasks, optionally filtered by project ID with a limit (default 30, max 200).
AI agents call list_completed_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 performs a read-only operation that retrieves completed tasks from Todoist without side effects. It accepts optional parameters (project ID, limit) for filtering results but does not create, modify, or delete any data. The low severity reflects minimal risk if misused by an AI agent, as listing completed tasks cannot cause harm or unintended consequences.
From the tool's definition Tool name 'list_completed_tasks' and description 'List completed tasks' indicate a retrieval operation with optional filtering. No modification, deletion, or execution occurs—the tool only queries and returns data.
Attacks that exploit this kind of access
List completed tasks, optionally filtered by project ID with a limit (default 30, max 200). 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_completed_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_completed_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_completed_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_completed_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_completed_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.
