What search_lei does on Tanod
AI agents call search_lei to retrieve information from Tanod without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
name | string | Yes | Company name to search in the GLEIF register, such as Bloomberg Finance. Matched against legal names first; when none match, a full-text search over names is us |
limit | integer | — | Most records to return, 1-20 (default 5). |
country | object | — | Optional ISO 3166-1 alpha-2 country code of the legal address, such as US or DE. |
Parameters from the server's own tool schema.
Why search_lei is rated Low
Even though search_lei only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs search_lei safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Tanod, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For search_lei, this is the rule to start with:
search_lei is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Tanod, apply this rule, and every search_lei call is checked against it from then on.
