# GLEIF API MCP

Vendor: GLEIF API  
Category: other  
Auth: NONE  
Composio slug: `gleif`

GLEIF provides free public access to Legal Entity Identifier records, ownership relationships, identifier mappings, and related reference data.

## Verdict

The GLEIF API MCP connects Switchy to the Global Legal Entity Identifier Foundation's registry of 2.5+ million business entities worldwide. @mention it to look up LEI records, verify corporate hierarchies, check parent-subsidiary relationships, or export entity data for compliance workflows. Finance and legal teams use it to validate counterparties, map ownership structures, and pull registration details without leaving the conversation. No authentication required — the registry is public — but fuzzy search and autocomplete can return unexpected matches if queries are vague.

## Tools

- **Export LEI Records** — Download up to 5,000 LEI records using the complete closed field-filter and sort surface as CSV, XLSX, JSON, or XML.
- **Get Autocompletions** — Return prefix-based GLEIF search suggestions from the provider's data collection, defaulting absent top-level metadata and links to empty objects. Highlighting is untrusted provider HTML and must be sanitized before rendering.
- **Get Fund or Branch Relationship** — Get the complete relationship record linking an LEI to its fund manager, umbrella fund, master fund, or head office.
- **Get Fuzzy Completions** — Find approximate GLEIF search matches for misspelled or incomplete input. Results are complete provider resources from the data-only collection when no top-level metadata or links are supplied; they are fragments, not full LEI records or pr
- **Get LEI Issuer for Record** — Get the complete LEI-issuer reference resource associated with a specified LEI record.
- **Get LEI Record** — Retrieve one LEI record with complete provider attributes, relationships, links, and Golden Copy metadata when its LEI is known.
- **Get Parent Information** — Get a direct or ultimate parent LEI plus complete relationship evidence, or the complete reporting exception when no parent is reported.
- **Get Reference Item** — Get one complete item from a selected GLEIF reference collection by its collection-specific identifier.
- **Get Related LEI Record** — Follow a selected associated-entity, managing-LOU, fund, or head-office link and return the complete related LEI record.
- **Get Successor Entity (Deprecated)** — Deprecated compatibility lookup that returns only the first successor LEI. Use GLEIF_LIST_SUCCESSOR_ENTITIES for complete current successor data.
- **List Child Entities** — List one page of complete direct or ultimate accounting-child LEI records.
- **List Child Relationships** — List one page of complete direct or ultimate accounting-child relationship records for an LEI.
- **List Fund or Branch Entities** — List one page of complete managed-fund, sub-fund, feeder-fund, or international-branch LEI records.
- **List Fund or Branch Relationships** — List one page of complete fund-management, sub-fund, feeder-fund, or international-branch relationship records.
- **List LEI Field Modifications** — List one page of complete LEI, relationship, or reporting-exception field-history resources with optional type, XPath, and date filters.
- **List LEI ISINs** — Return one page of complete GLEIF-ANNA ISIN mappings for an issuer LEI.
- **List LEI Issuer Jurisdictions** — List one page of complete jurisdiction resources for which an LEI issuer is accredited.
- **List Reference Data** — List one complete JSON:API page from a selected GLEIF field, code, or issuer reference collection. Use GLEIF_LIST_REGISTRATION_AGENTS for the unpaginated registration-agent collection.
- **List Registration Agents** — List all GLEIF registration agents, optionally filtered by issuer LEI or registration-agent LEI. This provider operation returns the complete collection and does not support pagination.
- **List Successor Entities** — List one page of all successor LEI records for an entity. Prefer this action over the deprecated GLEIF_GET_SUCCESSOR_ENTITY lookup.
- **Search LEI Records** — Search LEI records with closed, field-aware filters and sorting, returning one complete JSON:API page.
