time.parse · MCP: Risk & Policy

WHAT IT DOES

What time.parse does on Mcp

AI agents call time.parse to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why time.parse needs a policy

This is a pure data parsing utility that converts input timestamps/dates into various output formats. It performs no state changes, no code execution, no data modification, and no financial transactions. The zero-dependency nature and output-only behavior confirm it is a read operation with minimal risk.

From the tool's definition Tool description states it 'Parse[s] a timestamp or date string into canonical forms' and 'Returns' parsed components. The verb 'parse' and 'returns' indicate data retrieval/transformation with no side effects.

Questions about time.parse

What does the time.parse tool do? +

Parse a timestamp or date string into canonical forms — zero-dependency. Accepts unix seconds/millis or any standard date string (ISO-8601, RFC-2822, etc.). Returns UTC ISO, unix seconds + millis, RFC-2822, calendar components (year/month/day/hour/minute/second/weekday), ISO weekday, ISO year+week, and day-of-year. Pas. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on time.parse? +

Register the MCP server in PolicyLayer and add a rule for time.parse: 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 Mcp. Nothing to install.

What risk level is time.parse? +

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

Can I rate-limit time.parse? +

Yes. Add a rate_limit block to the time.parse 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.

How do I block time.parse completely? +

Set action: deny in the PolicyLayer policy for time.parse. 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 time.parse? +

time.parse is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
