SDK / MCP release status

A clear line between what is available today and what is not yet GA, so an integration is not built on the wrong assumption.

Release status matrix

The main entry point today is the public API gateway, authenticated with X-API-Key. The MCP server is live at https://mcp.twmarketdata.com/mcp. The SDKs remain preview, and the agent material is examples rather than a supported library.

Component	Status	Intended Use	Not Yet
Public API Gateway	Beta / Live	Direct API calls with X-API-Key	Rate limits GA
Python SDK	Preview	Local/dev usage	PyPI publish, tests
JavaScript SDK	Preview	Local/dev usage	npm publish, dual build
MCP Server	Beta / Live	Hosted MCP over streamable HTTP	stdio transport
AI Tool Manifest	Preview	Tool calling registry seed	Official agent runtime
Agent Examples	Example	Workflow demo	Investment advice / trading

The recommended path today

Production data requests: the public API gateway, `/v2/datasets/*` with `X-API-Key`.
SDKs: recommended for local and development use only.
MCP: the hosted server over streamable HTTP is live; there is no packaged stdio server.
Agent examples: they demonstrate a workflow. They are not investment advice, stock recommendations or trading signals.

Notes

The Python SDK is not published to PyPI and the JavaScript SDK is not published to npm.

For a production integration, build against the public API gateway documentation first.
