Query and return the User-Agent of specified profiles. Up to 10 profiles can be queried per request.
AI agents call get-profile-ua to retrieve information from TgeBrowser MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves User-Agent strings from browser profiles without modifying state, executing code, or causing side effects. It is a pure read operation querying existing profile metadata. The blast radius is minimal—User-Agent strings are typically non-sensitive configuration data, and there is no capability to modify profiles, execute code, or interact with external systems.
From the tool's definition Tool name 'get-profile-ua' and description 'Query and return the User-Agent of specified profiles' indicate a retrieval operation with no data modification, deletion, or execution of commands.
Attacks that exploit this kind of access
Query and return the User-Agent of specified profiles. Up to 10 profiles can be queried per request. It is categorised as a Read tool in the TgeBrowser MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TgeBrowser MCP Server MCP server in PolicyLayer and add a rule for get-profile-ua: 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 TgeBrowser MCP Server. Nothing to install.
get-profile-ua 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-profile-ua 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-profile-ua. 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-profile-ua is provided by the TgeBrowser MCP Server MCP server (tuguang2025/tgebrowser-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
