AI agents call get_job_role 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 job role data by identifier and returns information without modifying, executing code, or causing irreversible changes. It fits the Read category definition: retrieves or queries data with no side effects. Low severity because unauthorized access to job role metadata poses minimal risk compared to financial, destructive, or system-level operations.
From the tool's definition Tool description states 'Retrieve a single job role by id' and server is described as 'Read-only MCP server'. The verb 'retrieve' and the read-only designation confirm this is a data retrieval operation with no side effects.
Attacks that exploit this kind of access
Retrieve a single job role 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_job_role: 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_job_role 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_job_role 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_job_role. 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_job_role 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.
