MSCI provides investment decision-support tools, data, analytics, indexes, and sustainability research for the global investment community. Its products include APIs and related tooling for accessing index, ESG, risk, optimization, and other financial data and analytics.
MSCI exposes a developer portal of authenticated APIs, a Python SDK package (`msci.sdk`) for its Optimization Service/API access, and an OAuth-protected MCP server at `https://mcp.msci.com/mcp/v1.0/mcp`.

For MSCI APIs that use key-based auth, sign in to the MSCI Customer Center with your named-user or service-account credentials. If you already have an assigned API key, open the API Key section and click Generate Secret to create the one-time-visible secret. If you do not yet have access, go to the relevant API page in the MSCI Developer Community, click Get Access, wait for provisioning confirmation, then return to the Customer Center to generate the secret. Store both the API key and secret safely; the secret is shown only once.
For MSCI surfaces that use OAuth 2.0, first obtain access to the relevant API through the MSCI Developer Community / your MSCI representative. The ESG Data API documentation explicitly states it uses OAuth 2.0 token-based authorization, but the public docs we found do not expose the token acquisition steps or endpoints. After access is provisioned, follow the authenticated API documentation or MSCI support instructions to obtain an access token.
