# SBOR

SBOR lets an agent inspect bitcoin-backed borrowing rates and compare an offer with market benchmarks. Use it to check loan terms before acting.

## What it 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 `compare_rate` returns an error when data is over 48 hours old, a rate is missing, or an index is unpublished.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.

## Requirements
- Needs: Node.js (commands run via npx)
- Remote server: `https://mcp.sbor.xyz/mcp`

## When to use it
- 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
- 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.
