Common questions

Is SBOR safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.0) reached the registry 26 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

SBOR MCP server

Check a lending rate before your agent borrows.

SBOR publishes benchmark lending rates for borrowing against bitcoin, read from lending contract state and published daily: what it costs to borrow dollars against bitcoin, with a rate per stablecoin, and one borrow and one supply rate per currency on Stacks. This server exposes it as tools for Claude, Cowork, Cursor or any MCP client. Each day's fixing is also posted on-chain, on Arc, Base, Hyperliquid, Solana and Stacks.

Quick check

npx -y sbor-mcp

It starts and waits silently. That is success. Ctrl+C to exit.

Install

"mcpServers": { "sbor": { "command": "npx", "args": ["-y", "sbor-mcp"] } } }

Claude Desktop: add that to claude_desktop_config.json and restart.

Or connect by address, with nothing to install

https://mcp.sbor.xyz/mcp

Streamable HTTP, no key, no sign-in. Works as a custom connector in Claude on the web and in any MCP client that accepts a URL. The remote server is generated from this one, so both give the same answers.

Tools

Tool	What it answers
`get_rate`	What does capital cost on Stacks right now, and what does borrowing USDC against bitcoin cost
`compare_rate`	Is this offer above or below the market, and by how much
`list_markets`	Which venues make up the rate, with utilization and depth
`get_history`	How has the rate moved
`compare_chains`	How Stacks compares with Ethereum, Base, Hyperliquid, Solana and SOFR
`get_methodology`	How the number is built, and what it excludes

All six tools are read-only.

Benchmarks

From the fixing of 14 October 2026 (methodology 1.13.0, notice):

BTC-COLLATERAL-USD is the SBOR headline: what it costs to borrow any dollar stablecoin against plain 1:1 bitcoin, across every eligible market on Ethereum, Base, Arc, Arbitrum, BNB Chain and Stacks.
BTC-COLLATERAL-USDC, BTC-COLLATERAL-USDT, BTC-COLLATERAL-RLUSD, BTC-COLLATERAL-PYUSD and BTC-COLLATERAL-USD1 are the rates per stablecoin, each published once $25M or more of it carries weight. BTC-COLLATERAL-USDC keeps its name and history from 25 September 2026.
SBOR-USD, SBOR-BTC and SBOR-STX are the Stacks indices, unchanged.

To check a dollar loan against bitcoin, compare with the stablecoin's own rate where one is published, else with BTC-COLLATERAL-USD. Before 14 October, only BTC-COLLATERAL-USDC is published (Morpho on Base, Ethereum and Arc), and the other codes answer that they start on that date.

Recommended use

Use SBOR to stop, never to start. Before borrowing, call compare_rate. If the offer is more than 50 basis points above the benchmark, stop and ask a human. A wrong reading under that rule costs a pause, not a trade.

Behavior worth knowing

It refuses rather than guesses. compare_rate returns an error, not a verdict, when the data is more than 48 hours old, when the fixing timestamp cannot be read, when the index is not published, or when a rate is missing. An error means there is no trustworthy answer, not that the rate is bad. Fall back to your own logic.

It checks units. Rates are percentages: 4.2 means 4.2%. Anything outside 0 to 100 is rejected. Below 0.5 is answered, because rates that low genuinely occur, but with a warning that you may have passed a fraction.

It never averages across a methodology change. get_history gives a mean per methodology version when a window spans more than one.

It never guesses when SBOR is down. If SBOR is unreachable or slower than 10 seconds, the tool says so rather than substituting an estimate.

It reports omissions. When a market cannot be read, SBOR omits the index rather than publishing a figure it cannot stand behind. The tool explains that instead of returning nothing.

It surfaces concentration. An index covering one venue is a reading of that venue, not a market average, and get_rate says so.

It reads the same public endpoints as everyone else. No key, no state, no writes, no telemetry. Set SBOR_BASE to point at a different host.
