Parse an explicit user-agent string via POST /v3/user-agent. Paid only. Cost: 1 credit. Returns browser, device, OS, and engine details. This MCP tool parses only the uaString you pass. It does not infer a caller user-agent from the MCP transport. For multiple strings, use bulk_parse_user_agent.
Part of the Ipgeolocation Io server.
Free to start. No card required.
AI agents invoke parse_user_agent to trigger processes or run actions in Ipgeolocation Io. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
parse_user_agent can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access parse_user_agent gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Parse an explicit user-agent string via POST /v3/user-agent. Paid only. Cost: 1 credit. Returns browser, device, OS, and engine details. This MCP tool parses only the uaString you pass. It does not infer a caller user-agent from the MCP transport. For multiple strings, use bulk_parse_user_agent.. It is categorised as a Execute tool in the Ipgeolocation Io MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Ipgeolocation Io MCP server in PolicyLayer and add a rule for parse_user_agent: 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 Ipgeolocation Io. Nothing to install.
parse_user_agent is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the parse_user_agent 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 parse_user_agent. 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.
parse_user_agent is provided by the Ipgeolocation Io MCP server (ipgeolocation-io-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
