SBOR — Claude Code MCP server: rates and setup
SBOR lets an agent inspect bitcoin-backed borrowing rates and compare an offer with market benchmarks. Use it to check loan terms before acting.
claude mcp add --transport http sbor https://mcp.sbor.xyz/mcpWhat SBOR does
This MCP server reads published rates for loans backed by bitcoin, along with Stacks indices. Its six read-only tools can fetch a rate, compare an offer with the market, inspect venues and depth, review rate history, compare chains, or explain the methodology.
Connect over HTTP at https://mcp.sbor.xyz/mcp, or run the server with npx -y sbor-mcp. No API key is needed. compare_rate returns an error when data is over 48 hours old, a rate is missing, or an index is unpublished. If SBOR cannot be reached, it does not substitute an estimate. Treat that error as a lack of a trustworthy comparison, not as a judgement on the offer.
What it helps with
- compare a loan offer with a market benchmark
- find which venues contribute to a rate
- inspect market depth and utilization
- trace how a rate has changed
- compare Stacks indices with other chains and SOFR
Example prompts for the agent
- Compare this loan offer with the current SBOR benchmark and show the difference.
- List the venues behind this rate and show their market depth.
- Show how the rate changed over time and explain the methodology.

What does SBOR do?
It gives an MCP client read-only tools for bitcoin-backed borrowing rates, offer comparisons, rate history, chain comparisons, and methodology.
What happens when the rate data is stale?
compare_rate returns an error if the data is over 48 hours old or the rate cannot be read. It does not replace missing data with an estimate.
