Rates by 402rates is an MCP server with 9 tools an agent can call, among them cheapest_settlement_chain, compare_rwa_snapshots, compare_settlement_costs. It answers at https://api.402rates.com/mcp/rates over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Source-backed treasury data, settlement costs. Free instrument records and history.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
cheapest_settlement_chain | Returns only the single cheapest chain for a USDC transfer right now, its total transaction fee in USD, the scope of that figure and how long it stays valid. Free and deliberately minimal: no per-chain table, no runner-up, no fee components Inputs: chains |
compare_rwa_snapshots | Free comparison of two supplied 402rates Treasury snapshots: yield, issuer divergence, source identifiers, calculation windows and data availability. Reports numeric threshold crossings without assigning economic significance. No new data a Inputs: before, after, threshold_bps |
compare_settlement_costs | Measured USDC transfer costs on Base, Polygon, Arbitrum, Ethereum and XDC: simulated gas, current token prices, fresh chain heads and applicable rollup L1 fees. Inputs and block references accompany each figure. Cheapest first; unmeasurable Inputs: chains |
get_manifest | Free OpenAPI manifest for Rates by 402rates. Contains this product and shared service information only. Inputs: base_url |
get_rwa_history | Returns free normalized observations for one tracked instrument, one reconstructible recorder source and one inclusive date window. Every point carries value, date, source id, revision and source-time versus read-time dating. Omit source_id Inputs: ticker, source_id, date_from, date_to |
get_rwa_instrument | Returns the free frozen-contract state view for one tracked tokenized treasury: identity, Open Treasury Yield Basis result or explicit unavailable reason, issuer-term evidence cells, verified deployments and evidence dates. Three distinct t Inputs: ticker |
get_rwa_instruments | Complete evidence snapshot for 13 tokenized treasury funds: yield or gap, measured size, subscription/redemption minimums, fees, settlement, access conditions, chain conflicts, quotes, URLs and dates. Same records as the free instrument vie |
get_rwa_yields | Realised 30-day yields for 13 tokenized treasury funds under the Open Treasury Yield Basis. Measured rows use NAV, price or verified passive-holder balances, with observations, sources and dates. Issuer figures and differences appear where Inputs: instruments |
list_capabilities | Free capability and MCP tool catalogue for Rates by 402rates. Contains this product and shared service information only. |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://api.402rates.com/mcp/rates. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
