AI agents call get_psi_tasks to retrieve information from Timesheet Assistant MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves task data from PSI Project Server for display purposes only. It does not modify data, execute scripts, delete records, or commit financial transactions. The blast radius of misuse is minimal—an agent could retrieve task lists it shouldn't see, but this is an informational disclosure risk rather than destructive or operational risk.
From the tool's definition Tool description states it 'fetches the hierarchical task list and returns instructions for the LLM to display it to the user' and is explicitly framed as an ORCHESTRATION TOOL for retrieval.

ORCHESTRATION TOOL: Get available tasks from PSI Project Server for a specific date and present them to user. This tool fetches the hierarchical task list and returns instructions for the LLM to display it to the user in the same hierarchical tree format.\n\nWHEN TO USE: Use this tool when user wants to fill PSI timesheet. First get tasks, then ask user to select a task by its index number.\n\nOPTIMIZATION: The task list is the SAME for all days in a timesheet period. Call this tool ONCE when starting to submit a multi-day timesheet, NOT once per day. Reuse the same task index for all days in the timesheet.\n\nIMPORTANT: After calling this tool, the LLM MUST present the Hierarchical Tree View to the user exactly as provided by the tool, then ask which task index they want to use. It is categorised as a Read tool in the Timesheet Assistant MCP MCP Server, which means it retrieves data without modifying state.
Register the Timesheet Assistant MCP server in PolicyLayer and add a rule for get_psi_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 Timesheet Assistant MCP. Nothing to install.
get_psi_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 get_psi_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 get_psi_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.
get_psi_tasks is provided by the Timesheet Assistant MCP server (sharadmathuratthepsi/timesheet-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
