Available tools 24

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_payment_terms

Free comparison of two unsigned captures for the same resource and method. Default analysis version 1 retains Exact EVM; version 2 compares documented Exact, Upto, Batch Settlement and Auth-Capture fields, limits and lifecycle terms. Captures are caller declarations, with no authentication, fetching or payment. Unknown profiles remain non-comparable.

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.

agent

list_agent_test_cases

Free catalogue of versioned synthetic cases: unavailable confirmation, retry credits and attempt limits, and partial results with continuation. No run, wallet or payment.

read_agent_test_report

Read calls, timestamps, operations and resulting state. Optional finalization freezes the run. A linked repeat includes the previous frozen report while retained. No score, certification or judgment of the agent.

capabilities

list_capabilities

Returns the live 402rates.com capability catalogue: capability id, HTTP path, price in USDC, description, input schema and freshness policy for each. Free, and the same catalogue the paid tools and the HTTP manifest are generated from.

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.

decode

decode_payment_attribution

Free local decoding of an ERC-8021 schema-2 x402 builder-code suffix from supplied calldata. Separates application, facilitator, services and facilitator-reported metadata. No transaction lookup, receipt confirmation, identity verification or payment. Malformed and unsupported suffixes remain explicit.

describe

describe_agent_test

Free description of a versioned synthetic task, its limits and coverage. Optional case selection; omitted selection describes the original confirmation case. No run, payment or wallet.

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.

execute

execute_test_action

Execute the selected case's action: synthetic order, retry attempt, page retrieval or result submission. Identical keys and input replay the stored outcome. Calls, effects and simulated credits remain observable. No real payment.

inspect

inspect_test_state

Read operation records for a synthetic task. Observation timestamps and state describe the test service only. No claim about client receipt or overall agent reliability.

manifest

get_manifest

Returns the machine-readable OpenAPI 3.1 manifest of 402rates.com, including per-operation x-payment-info with prices, networks and payment addresses. Free, and byte-identical to the document served at /v1/manifest.

payment

check_payment_terms

Free inspection of unsigned x402 terms. Default analysis version 1 retains Exact EVM checks; analysis_version 2 inspects documented EVM Exact, Upto, Batch Settlement and Auth-Capture profiles, declared limits and lifecycle fields. Unknown fields stay unchecked. No wallet, signature verification, live contract validation or settlement.

start

start_agent_test

Create a free bounded synthetic run without an account. An optional finalized previous run and its token link a repeat of the same case version and scenario. No real purchase. Caller model costs remain external.

test

test_payment

Payment integration check for 0.001 USDC; no external data lookup. Returns time, rail, network mode and free/paid capabilities. HTTP payment options can include Base, Polygon, Arbitrum and XDC; the challenge lists currently available networks for each transport. The receipt identifies the paid network and transaction. Business/professional use only. Terms: https://402rates.com/data-terms/ Price: 0.001 USDC per call over x402.

x402

find_x402_resource

Searches the x402 resource catalogue and returns matching paid endpoints with their price, the chains they accept, and their 30-day usage from the catalogue's own counters: total calls, distinct paying addresses, the ratio between the two, and days since the last payment. Every figure is a count and carries its definition; no entry is scored, rated or labelled. Answers from a dated weekly snapshot and states which day it is from. Free.

Compass by 402rates — questions

Answers built from our own checks of this server.

What can Compass by 402rates do?

It exposes 24 tools, read directly from the server on our last check. Among them: cheapest_settlement_chain, check_payment_terms, compare_payment_terms, compare_rwa_benchmark, compare_rwa_snapshots, compare_settlement_costs and 18 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Compass by 402rates mostly used for?

Its tools cluster around rwa, compare and agent. 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 Compass by 402rates working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 182 of 182 checks got a reply (100.0%), average response time 194 ms. The bar chart above shows every period we have measured.

How do I connect Compass 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 Compass by 402rates need an API key?

No. Compass by 402rates completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 24 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Compass by 402rates?

It answers our handshake in 194 ms on average, which is faster than 80% 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.
