Bundesbank
German government bond yields from the Deutsche Bundesbank — the daily term structure of listed Federal securities, one to thirty years, where FRED carries only a monthly figure.

About
Bunds are the euro area's risk-free benchmark, and the Bundesbank estimates their whole curve every business day — the term structure of interest rates on listed Federal securities, one to thirty years. European valuations discount against it, and it sets the rate backdrop those companies report into. FRED carries a German long-term yield as well, but monthly and compiled by the OECD, where this is the central bank's own daily figure. Reproduction is permitted where the source is stated, so answers state it.
Nothing to set up, and no key to bring. Marvin Labs runs this connector against a public endpoint that takes no credential, so it is on unless you turn it off under Connectors in settings.

Frequently asked questions
- What is a Connector?
- A Connector is an MCP server that Marvin Labs runs and authenticates. There is no URL to paste and no key to find: Bundesbank is on for your account unless you turn it off. 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 Bundesbank Connector require authentication?
- No. Marvin Labs holds the Bundesbank credentials and signs every request, so there is nothing to set up.
- Does Bundesbank 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. Bundesbank is used only when a question needs data those documents do not carry, and the answer attributes that output to it.
- Where is Bundesbank 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.
