The Gleif MCP Server, developed by Olgasafonova for the mcp platform, is built with Go, requiring Go 1.25+ for source compilation. This free MCP server provides access to Legal Entity Identifier (LEI) data by connecting to the public GLEIF API. It offers a suite of tools for verifying legal identities and is distributed as pre-compiled binaries for various systems, making it accessible for developers and entities needing compliance and due diligence support.

What does Gleif MCP Server connect to?

The Gleif MCP Server functions as an MCP server, specializing in access to LEI database information. It establishes a connection to the public Global Legal Entity Identifier Foundation API. This connection is specifically directed to https://api.gleif.org/api/v1, enabling the server to retrieve and process Legal Entity Identifier data. Its primary role is to act as a gateway to this crucial public resource, categorizing it as an MCP server dedicated to legal entity data.

Core features and tools

Gleif MCP Server exposes several callable tools designed for legal entity data interaction. These include LEI Lookup for individual identification, Batch Lookup for multiple queries, and Entity Search for broad investigations. It also offers LEI Validation for compliance, BIC/SWIFT Lookup for financial codes, and ISIN Lookup for security identification.
