How do I install the SBOR MCP server?
SBOR runs locally as an npm package, launched with npx -y sbor-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
compare_chains Compare Stacks rates against the same markets on other chains ~125
The same asset classes on the largest lending markets on Ethereum, Base, Hyperliquid and Solana, plus SOFR, the US repo rate, and what it costs to borrow USDC against bitcoin on Base and Ethereum. Context only: none of these is ever a constituent of an SBOR index. Aave on Ethereum and Base and the bitcoin-collateral markets are read from contract state; the other venues come from DefiLlama, so small differences are expected for those.
| Name | Type | Req | Description |
|---|---|---|---|
| index | string | – | Only markets comparable to this index. Omit for all. |
No output schema declared.
No examples provided.
compare_rate Compare a rate against the SBOR benchmark ~227
Given a rate you have been offered, say whether it is above or below the market for that currency, and by how much. This is the main reason SBOR exists. Recommended use: if a borrow offer is more than 50 basis points above the benchmark, stop and ask a human. Use SBOR to stop, never to start. For a USDC loan against bitcoin (cbBTC or WBTC) on Base or Ethereum, compare with BTC-COLLATERAL-USDC; for lending on Stacks, with the index for the currency. This tool refuses rather than guesses: an error result means there is no trustworthy answer, not that the rate is bad.
| Name | Type | Req | Description |
|---|---|---|---|
| index | string | yes | Which benchmark: a Stacks currency index, or BTC-COLLATERAL-USDC for borrowing USDC against bitcoin on Base and Ethereum. |
| rate | number | yes | The rate offered, as a percentage between 0 and 100. 4.2 means 4.2%, not 0.042. |
| side | string | yes | Whether you would be borrowing or supplying. |
No output schema declared.
No examples provided.
get_history Get the SBOR history ~82
Daily fixings since the index began. Use this to see whether a rate is unusual, or how the cost of capital has moved. Means are given per methodology version, never across a change in how the number is built.
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | – | How many days back, up to 200. Default 30. |
| index | string | yes | Which currency. |
No output schema declared.
No examples provided.
get_methodology How SBOR is calculated ~49
The full methodology and integration policy: how the fixing is built, what is excluded and why, and what SBOR will and will not do. Read this before quoting a rate in anything that matters.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_rate Get the current SBOR fixing ~111
The benchmark borrow and supply rate for lending on Stacks, read from lending contract state. Use this to judge whether a lending offer is good: borrowing above the SBOR borrow rate means paying more than the market, supplying below the supply rate means earning less. Returns every currency index unless one is named. Always read the freshness line first.
| Name | Type | Req | Description |
|---|---|---|---|
| index | string | – | Currency index, or BTC-COLLATERAL-USDC for borrowing USDC against bitcoin on Base and Ethereum. Omit for all of them. |
No output schema declared.
No examples provided.
list_markets List the lending markets behind a rate ~68
Every venue and asset in an index, with its borrow rate, supply rate, utilization, depth and weight. Utilization explains why a rate sits where it does.
| Name | Type | Req | Description |
|---|---|---|---|
| index | string | – | Currency index, or BTC-COLLATERAL-USDC. Omit for the Stacks indices. |
No output schema declared.
No examples provided.
What is the SBOR MCP server?

Is the SBOR MCP server safe to use?
SBOR scores 71 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 25 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the SBOR MCP server expose?
SBOR exposes 6 tools: get_rate, compare_rate, list_markets, get_history, compare_chains, get_methodology. Their descriptions and schemas cost roughly 662 tokens of context every time the server is loaded.
Is the SBOR MCP server still maintained?
SBOR is still listed as active in the MCP registry. We last reached this channel on 25 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
