Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 11 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability78
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1241 tokens (~112/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management57
- Stability observed for 17 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the Rates by 402rates MCP server?
Rates by 402rates is a hosted endpoint at https://api.402rates.com/mcp/rates, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

cheapest_settlement_chain Cheapest chain for a USDC transfer ~109
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.
| Name | Type | Req | Description |
|---|---|---|---|
| chains | string | – | comma-separated subset of base, polygon, arbitrum, ethereum, xdc. Defaults to all five. |
No output schema declared.
No examples provided.
compare_rwa_benchmark Compare a supplied USD Treasury return with a matching benchmark ~146
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.
| Name | Type | Req | Description |
|---|---|---|---|
| benchmark | object | – | kind us_treasury_total_return_index, currency USD, start_date/end_date, positive start_value/end_value, HTTPS source_url and retrieved_at date. Caller declarations only. |
| snapshot | object | – | Saved single-instrument response, schema_version 0.5.0, with a measured USD return. |
No output schema declared.
No examples provided.
compare_rwa_snapshots Compare yield and divergence fields in two saved Treasury responses ~137
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.
| Name | Type | Req | Description |
|---|---|---|---|
| after | object | – | Later saved response. Input origin is not independently authenticated. |
| before | object | – | Earlier saved yields, single instrument or complete instrument response; schema_version 0.5.0. |
| threshold_bps | number | – | Absolute change in issuer_vs_basis_bps to flag, default 5; zero flags only nonzero changes. |
No output schema declared.
No examples provided.
compare_settlement_costs Measured cost of a USDC transfer per chain, cheapest first ~130
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.
| Name | Type | Req | Description |

get_rwa_history Get one RWA source history ~191
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.
| Name | Type | Req | Description |
|---|---|---|---|
| date_from | string | – | inclusive first observation date in YYYY-MM-DD form; required with source_id |
| date_to | string | – | inclusive last observation date in YYYY-MM-DD form; required with source_id |
| source_id | string | – | one source id belonging to ticker. Omit it to list that instrument's sources without observations. |
| ticker | string | – | tracked instrument ticker, case-insensitive. Omit it to list tickers and audited history sources. |
No output schema declared.
No examples provided.
get_rwa_instrument Get one RWA instrument state ~116
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.
| Name | Type | Req | Description |
|---|---|---|---|
| ticker | string | – | tracked instrument ticker, case-insensitive. Omit it to receive the complete known ticker list. |
No output schema declared.

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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_rwa_yields Realised 30-day yields of tokenized treasuries, recomputable ~127
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.
| Name | Type | Req | Description |
