The three tools split cleanly by input key: lookup_company takes a legal name, lookup_lei takes a single 20-char LEI, and bulk_lookup handles many queries. There is mild overlap since bulk_lookup accepts both LEI and 'name | CC' formats, but the single-vs-batch boundary is clear enough to guide selection.

All names are snake_case and start with a lookup verb, giving a predictable read (lookup_company, lookup_lei). The only minor deviation is bulk_lookup, which drops the 'lookup_' prefix for the batch variant, but it remains understandable.

Three tools is slightly lean but well-matched to a focused GLEIF data-access service: one per lookup mode (name, LEI, batch). Each tool earns its place without redundancy, though the surface is minimal.

Core GLEIF access is covered: name search, single-LEI resolution, and batch lookup, all returning status, addresses and parents. Minor gaps exist (e.g. no reverse/parent-tree traversal or pagination/filter options), but agents can work around these by chaining lookups.
