# ChainIT public integration docs

> ChainIT provides identity verification (KYC, KYB), hosted UI authentication, and verified data
> transactions through its APIs. Developers register applications in the Developer Portal, obtain
> a clientId and clientSecret, and integrate through M2M (server-to-server), IDP (OAuth/OIDC
> login), or Hosted UI (managed sign-in and verification screens through a frontend SDK).

ChainIT runs a read-only MCP server for AI coding agents at https://sdk-mcp.chainithub.com/mcp
(streamable HTTP, no auth). Install with:
`claude mcp add --transport http chainit-sdk https://sdk-mcp.chainithub.com/mcp`
It answers with the canonical SDK package (`@chainitservices/hosted-ui`, pin `^1.0.1`), real
symbol declarations, and vetted scaffold files.
