# MSCI

> MSCI provides critical decision support tools and services for the global investment community: indexes, ESG and climate ratings, risk analytics, real estate and private asset data. The MSCI Developer Community (developer.msci.com) catalogs thirty-plus REST APIs, an official Python SDK, and the MSCI Connector — a Model Context Protocol server listed in the Claude connector directory. API access requires MSCI client credentials (accounts.msci.com OAuth 2.0 / OIDC); data is entitlement-controlled per MSCI license.
