Gleif Mcp Server

What is Gleif Mcp Server?

Gleif Mcp Server is an MCP server that gives AI assistants direct access to the Global Legal Entity Identifier (LEI) database via GLEIF's public API. It enables lookup of company identities, verification of legal entities, and exploration of corporate ownership structures, and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and other MCP-compatible tools.

How to use Gleif Mcp Server?

Download the pre-built binary for your platform from the releases page, make it executable, then configure your MCP client (e.g., Claude Desktop, Cursor) to point to the binary path in the appropriate JSON config file. No API key is required; the server works out of the box with GLEIF's public API.

FAQ from Gleif Mcp Server

Do I need an API key to use Gleif Mcp Server?

No. The server uses GLEIF’s public API which requires no authentication, so it works out of the box.

What are the rate limits and how does the server handle errors?

GLEIF allows 60 requests per minute; the server limits itself to 50 req/min and automatically retries on rate‑limited, timeout, or network errors (up to 3 attempts with exponential backoff). Structured error codes (e.g., not_found, rate_limited) indicate retryability.

How current is the data? If a LEI looks valid but is not found, what’s wrong?

The GLEIF database updates daily; recently issued LEIs may not appear immediately. Also verify the LEI is exactly 20 alphanumeric characters and follows ISO 17442 format.

What transport does Gleif Mcp Server use?

It uses the stdio transport, configured by specifying the binary path in your MCP client’s JSON configuration file.

Can I look up multiple LEIs at once?

Yes. The batch_lei_lookup tool accepts up to 100 comma‑separated LEI codes in a single request.
