Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
rwa
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 to list the instrument's audited sources. The five current-only issuer series return HISTORY_SOURCE_RESERVED with the data-use URL, never an empty gap. Shares the instrument view's three-ticker rolling-hour breadth limit.
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 tickers are free per caller in a rolling hour; repeats stay free, and the fourth returns BREADTH_LIMIT with the paid complete-snapshot path. An omitted ticker returns only the known ticker list.
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 view. Internal use with attribution included; continuous access, change notices and customer-facing use are separate. Business/professional use only. Terms: https://402rates.com/data-terms/ Price: 5 USDC per call over x402.
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 available. Quoted and unavailable rows stay explicit; free coverage lists funds and gaps. Business/professional use only. Terms: https://402rates.com/data-terms/ Price: 0.03 USDC per call over x402.
list_rwa_updates
Free cursor-based Treasury change notices. Instrument scope retains version 1; market and access scopes use version 2 and independent cursors. Source dates and digests remain distinct from retrieval times. Up to 90-day retention subject to source permissions. No paid market values or reconstruction before the first baseline.
read_rwa_access_evidence
Free source-backed documentation of Treasury distribution and asset-settlement protocols. Distinguishes an announced access path from an identified fund and a protocol from a deployed fund integration. Unknown fund identity, investor access and liquidity remain explicit. No live quote, execution or eligibility determination.
compare
compare_rwa_benchmark
Free arithmetic comparison of a saved measured USD instrument response and caller-supplied US Treasury total-return index levels with identical dates. Simple actual/365; 28-32 days. Input provenance is not verified. Spot rates, unmatched windows, quoted yields and other currencies are not comparable. The spread does not establish fees or causality.
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 access, authentication of snapshots, historical reconstruction or automatic monitoring. Examples are synthetic.
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 chains are excluded, not estimated. Business/professional use only. Terms: https://402rates.com/data-terms/ Price: 0.01 USDC per call over x402.
capabilities
list_capabilities
Free capability and MCP tool catalogue for Rates by 402rates. Contains this product and shared service information only.
cheapest
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 and no source provenance. The paid tool compare_settlement_costs returns the full comparison with every input disclosed.
estimate
estimate_payment_costs
Free exact-decimal calculation from caller-supplied prices, fees and setup costs for a planned number of calls. Separates locked capital and batches; unknown costs stay unknown. Compares complete profiles only within the same currency. No exchange-rate conversion, external fee measurement, payment or verification of supplied inputs.
manifest
get_manifest
Free OpenAPI manifest for Rates by 402rates. Contains this product and shared service information only.

Among them: cheapest_settlement_chain, compare_rwa_benchmark, compare_rwa_snapshots, compare_settlement_costs, estimate_payment_costs, get_manifest and 7 more.

How MCP servers expose tools in the first place →
What is Rates by 402rates mostly used for?
Its tools cluster around rwa and compare. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Rates by 402rates working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 175 ms. The bar chart above shows every period we have measured.
How do I connect Rates by 402rates?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Rates by 402rates need an API key?
No. Rates by 402rates completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 13 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Rates by 402rates?
It answers our handshake in 175 ms on average, which is faster than 77% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
