Return market scanner parameter definitions.
AI agents call ibkr_get_scanner_params to retrieve information from Ibkr without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves static parameter definitions for market scanners—metadata that defines what filtering options are available. It performs no side effects, no code execution, no data modification, and no financial transactions. The tool is purely informational and returns configuration/reference data.

{
"version": "1",
"default": "deny",
"tools": {
"ibkr_get_scanner_params": {}
}

Return market scanner parameter definitions. It is categorised as a Read tool in the Ibkr MCP Server, which means it retrieves data without modifying state.
Register the Ibkr MCP server in PolicyLayer and add a rule for ibkr_get_scanner_params: 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 Ibkr. Nothing to install.
ibkr_get_scanner_params is a Read tool with low risk. Read-only tools are generally safe to allow by default.

ibkr_get_scanner_params is provided by the Ibkr MCP server (patrickpxp/ibkr-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Ibkr, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
