Adds or subtracts a duration from a given timestamp
AI agents call adjust_timestamp to retrieve information from Temporal Awareness 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 pure date/time arithmetic calculation — it computes an adjusted timestamp by adding or subtracting a duration. It has no side effects, does not modify any stored data, and simply returns a computed value. It fits squarely in the Read category as a query/calculation operation.

Attacks that exploit this kind of access
Adds or subtracts a duration from a given timestamp. It is categorised as a Read tool in the Temporal Awareness MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Temporal Awareness MCP Server MCP server in PolicyLayer and add a rule for adjust_timestamp: 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 Temporal Awareness MCP Server. Nothing to install.
adjust_timestamp 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 adjust_timestamp 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 adjust_timestamp. 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.
adjust_timestamp is provided by the Temporal Awareness MCP Server MCP server (pmbstyle/temporal-awareness-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
