## Example call (MCP tools/call, JSON-RPC 2.0)

```json

  "jsonrpc": "2.0",

## Why business.id-resolve is rated Low

This tool only looks up and returns company legal entity information (identifiers, jurisdiction, canonical name) from external registries (SEC, GLEIF). There are no write, execute, destructive, or financial side effects. Severity is low as the worst-case misuse is retrieving publicly available company data.

From the tool's own definition: "'Company legal-entity resolver: give one of name, lei, cik, or ticker → LEI, CIK, ticker(s), jurisdiction, canonical name' — purely resolves and retrieves company identity data from SEC and GLEIF."

## Use case

AI agents call business.id-resolve to retrieve information from Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mcp:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "business.id-resolve": {}
  }
}
```
