Connect GLEIF (LEI) to Copilot Studio
Query GLEIF (LEI) directly from Copilot Studio. Arlet links the two through one MCP connection and takes care of API keys.
Connects your AI client to the GLEIF API v1 (the operator of the global LEI system).
Tools:
- search_lei_records: full-text search by company name. Returns LEI, legal name, jurisdiction and status.
- get_lei_record: one entity record by its 20-character LEI.
- get_lei_ownership: the reported direct parent and ultimate parent of an entity. Note that a missing parent means none is *reported* to GLEIF, not necessarily that none exists.
LEI is the cross-reference hub for other corporate data sources (it also carries BIC and other identifier mappings), which makes this server useful together with jurisdiction-specific corporate registries.
