Third-party
Cross-asset pricing, curves and analytics

About
LSEG's Financial Analytics data is cross-asset pricing and the curves behind it: bond and bond-future prices, FX spot and forwards, interest-rate, inflation and credit curves, swaps, options with Greeks, FX and equity volatility surfaces, IBES consensus estimates and historical time series. It is for pricing an instrument or reading a curve inside the thread instead of in a spreadsheet.
Access is arranged with LSEG, not self-served, and what you can price follows your entitlements. With an LSEG account that has it, click Add and sign in when the window opens.

Frequently asked questions
- What is a Connector?
- A Connector is a remote MCP server that a third party runs and Marvin Labs knows how to reach. Marvin Labs supplies the endpoint and the setup; you bring your own LSEG account. Once added, AI Analyst Chat and Deep Research Agents call its tools when a question needs them, and the answer shows which tool was called and what it returned.
- Does the LSEG Connector require authentication?
- Yes. Adding LSEG opens its sign-in window, where you approve access with your own LSEG account. Marvin Labs never sees your password; LSEG issues a token you can revoke on its side at any time.
- Does LSEG change how financial data is sourced?
- No. When a question can be answered from the filings, earnings calls, and press releases Marvin Labs ingests through Automated Data Import, it answers from those. LSEG is used only when a question needs data those documents do not carry, and the answer attributes that output to it.
- Where is LSEG available?
- In both AI Analyst Chat and Deep Research Agents. Its tools stay out of the model's context until a request needs one, so an unused Connector takes up no context window.
