AI agents call get_user to retrieve information from AdButler without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
user_id | string | Yes | User ID |
user_db_id | number | Yes | User database ID |
Parameters from the server's own tool schema.
This tool retrieves data about a single user without creating, modifying, deleting, or executing operations. It is a straightforward read operation with minimal blast radius if misused—an AI agent could query user records but cannot alter data or trigger external actions. Low severity is appropriate for read-only data retrieval in an ad management context.
From the tool's definition Tool name 'get_user' and description 'Get a single user from a user database' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Get a single user from a user database. It is categorised as a Read tool in the AdButler MCP Server, which means it retrieves data without modifying state.
get_user accepts 2 parameters: user_id, user_db_id. Required: user_id, user_db_id. The full parameter table on this page comes from the server's own tool schema.
Register the AdButler MCP server in PolicyLayer and add a rule for get_user: 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 AdButler. Nothing to install.
get_user 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_user 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_user. 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_user is provided by the AdButler MCP server (adbutler/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
