AI agents call get_time_away to retrieve information from Humaans without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns time-away data without modifying, creating, or deleting any records. It performs a simple lookup operation, which is a classic Read category action. The read-only nature of the server and lack of any destructive or modifying capability further support the Read classification with high confidence.
From the tool's definition Tool description states 'Retrieve a single time-away record by id' and server is explicitly described as 'Read-only MCP server'. The verb 'Retrieve' and the read-only server designation confirm this is a data retrieval operation with no side effects.
Attacks that exploit this kind of access
Retrieve a single time-away record by id. It is categorised as a Read tool in the Humaans MCP Server, which means it retrieves data without modifying state.
Register the Humaans MCP server in PolicyLayer and add a rule for get_time_away: 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 Humaans. Nothing to install.
get_time_away 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_time_away 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_time_away. 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_time_away is provided by the Humaans MCP server (ptorsten/humaans-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
