Connect Compass by 402rates and your agent gets 17 tools, among them cheapest_settlement_chain, check_payment_terms, compare_rwa_snapshots. It answers at https://api.402rates.com/mcp/compass 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 18 October 2026, succeeded.
Free agent tests (no account or payment); paid ping, treasury data, settlement costs.
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 |
check_payment_terms | Free inspection of supplied x402 v1/v2 payment terms against the SDK schema and optional network, asset, recipient and atomic budget constraints. Exact EVM profile checks only. No wallet connection, external fetch, signature verification or Inputs: challenge, expected |
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 |
describe_agent_test | Free description of one versioned synthetic task, its limits and coverage. No run is created. No payment or wallet is involved. |
execute_test_action | Create a synthetic operation for a run. The first committed action replaces its confirmation with an application-level error. Identical keys and payloads replay the stored operation; new keys can create more operations. No real purchase or Inputs: run_id, task_id, action_key, quantity, access_token |
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, Inputs: q, max_price, network, limit |
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. 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 |
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. Inputs: run_id, task_id, access_token |
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. |
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. Inputs: run_id, finalize, access_token |
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. No real purchase. Caller model costs remain external. Inputs: case_id, case_version, previous_run_id, configuration_changed, access_token |
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 networ |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://api.402rates.com/mcp/compass. 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.
