Calculate the difference between two timestamps.
AI agents call time_difference to retrieve information from MCP Server Framework without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a mathematical calculation on timestamp inputs to produce a time difference result. It has no side effects, does not modify data, does not execute arbitrary code or shell commands, and does not delete or move resources. It is analogous to a search or fetch operation in that it retrieves derived information based on inputs.
From the tool's definition Tool name 'time_difference' and description 'Calculate the difference between two timestamps' indicate a pure computation/query operation that retrieves or derives information from provided timestamps without modifying any data or triggering external…
Attacks that exploit this kind of access
Calculate the difference between two timestamps. It is categorised as a Read tool in the MCP Server Framework MCP Server, which means it retrieves data without modifying state.
Register the MCP Server Framework MCP server in PolicyLayer and add a rule for time_difference: 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 Server Framework. Nothing to install.
time_difference 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 time_difference 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 time_difference. 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.
time_difference is provided by the MCP Server Framework MCP server (tim-akkio/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
