A side-by-side look at the Stablecoin Scanner (StableScan) and Goldbean MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Stablecoin Scanner (StableScan) for finance & fintech work over a hosted endpoint; choose Goldbean for finance & fintech as a local process. You can also run both side by side in one mcpServers block.
get_address_approvals, get_address_compliance, get_address_exposure.fetch, get_balance, list_accounts.Rows where the two servers differ are marked.

get_address_approvalsOpen ERC-20 and Permit2 allowances one address has granted on one chain, one row per spender and token with the raw value, unlimited/oversized/old flags, spender_class and a band (critical|high|low|expired|none): unlimited to a flagged or unknown spender is the main drain vector, a known service spender (DEX router, Permit2) is normal, an expired Permit2 sub-allowance reads 'expired'. Use it when the question is what a wallet has approved and who could pull its stablecoins. Not for a risk tier — the band is informational and never moves get_address_risk. Not for issuer freezes: get_address_compliance. Not for taint: get_address_exposure. address is the allowance owner (the granter), never the spender. Heavy read: under load it answers busy or timeout — retry with backoff. No auth; 1200 requests/min shared by all tools. A heuristic band over decoded on-chain Approval facts, not an AML or legal determination.get_address_complianceIssuer freeze/seize facts for one address on one chain, plus the OFAC SDN flag: freeze[] (one row per freeze-capable stablecoin, status frozen|seized|clear|unknown, with frozen_usd6 = the balance locked now where it was read), not_freezable[] (stablecoins whose issuer cannot freeze on this chain, e.g. the Binance-Peg wrappers on BNB Chain — enforcement is off-chain), frozen_elsewhere[] (the same address bytes under a standing freeze on another indexed chain; EVM and Tron share them, Solana never) and freeze_proposals[] (issuer multisig proposals naming the address, USDT on Ethereum and Tron: executed ones, pending only where the operator publishes them). Use it when the question is whether an issuer or OFAC acted on this address, or how much is frozen. Not for a risk tier: get_address_risk. Not for taint distance: get_address_exposure. Not for when the OFAC list was refreshed: get_sanctions_status. Decoded on-chain issuer acts with provenance, no heuristics. 'unknown' means no act names the address and that pair's freeze history is not fully backfilled yet — absence of evidence is not 'not frozen'; an empty frozen_elsewhere[] or freeze_proposals[] means none in what is indexed, not clean everywhere. Each chain is its own issuer act: pass chain to ask Ethereum or Tron about the same bytes, chains_with_data says where. Heavy read: under load it answers busy or timeout — retry with backoff. No auth; 1200 requests/min shared by all tools. Not an identity, AML or legal determination.get_address_exposureTaint exposure of one address on one chain: a bounded backward walk over the value graph to the nearest OFAC-sanctioned or hack/drainer/mixer root, answered as a class (sanctioned|direct|indirect|negligible|unknown|none), the nearest hop and a value-proportional haircut fraction. Use it to explain how closely an address is tied to a sanctioned or hack root and by how much value. Not for one go/no-go tier — get_address_risk already includes this walk. Not for the counterparties themselves or a chosen depth, token or window: get_wallet_graph_walk. Not for issuer freezes: get_address_compliance. 'unknown' means the walk did not complete — OFAC list unloaded, time_budget, frontier_cap, Solana coverage pending or partial, short history, or no hack/drainer/mixer label loaded for this chain — never a false 'none'; incomplete_reasons names which (time_budget may complete at a quieter moment, frontier_cap repeats). Depth is fixed at 3 hops and the walk never crosses chains: ask again with chain set for each network in chains_with_data. A verdict is reused for up to 60 s (10 s after a time_budget cut). Heavy read: under load it answers busy or timeout — retry with backoff. No auth; 1200 requests/min shared by all tools. A heuristic signal, not an AML or legal determination.get_address_riskUnified risk tier for one address on one chain — unknown|none|low|medium|high|severe — from decoded facts (OFAC listing, issuer freeze/seize on this chain, exposure to a sanctioned or hack root) and attributed labels with provenance (labels alone cap at medium; a lone-source accusation adds no tier). Use it for one go/no-go read before accepting or sending funds. Not for freeze proposals, frozen balances or a freeze on another chain (frozen_elsewhere): get_address_compliance. Not for taint hops or the haircut: get_address_exposure. Not for open allowances: get_address_approvals. 'unknown' means the check did not finish, never 'checked clean'; evidence and incomplete_reasons name the cause (e.g. time_budget: the exposure walk was cut, a quieter moment may complete it). The freeze input is this chain's per-token status alone: frozen/seized argues for high, and an 'unknown' status or a pair whose freeze history is not backfilled turns a would-be 'none' into 'unknown' — so a Solana tier, where every freeze pair is unknown, is never 'none'. The exposure walk behind the tier is fixed at 3 hops; pick depth and window with get_wallet_graph_walk. A verdict is reused for up to 60 s (10 s after a time_budget cut). Heavy read: under load it answers busy or timeout — retry with backoff. No auth; 1200 requests/min shared by all tools. Not an identity, AML or legal determination.get_recent_transactionsRecent stablecoin transfers on one chain, newest first, filterable by payer and/or recipient, cursor-paginated. Use it for the latest transfers of an address or of the whole chain, with a tx_hash to cite. Not for who an address settles with over time: get_wallet_graph_walk. Not for how fresh the feed is: get_sync_status. Not for any verdict about an address: get_address_risk. Answer: items[], each row tx_hash, log_index, block_number, block_time (RFC 3339), payer, recipient, amount {amount (minor units, string), decimals, token (symbol)}, token (the contract address), finality, and usd_amount where priced. The chain is the one asked for — rows do not repeat it. payer and recipient narrow together; omit both for the chain-wide feed; pass next_cursor back unchanged as cursor for older rows, and a page without it is the last. Heavy read: under load it answers busy or timeout — retry with backoff. No auth; 1200 requests/min shared by all tools. Plain on-chain Transfer facts, no scoring.get_sanctions_statusOFAC SDN list coverage as this scanner holds it: evm_count, solana_count, tron_count and total addresses loaded (the free public 0xB10C list of US-Government public-domain data), updated_at of the last refresh (null until the first ingest) and the source. Use it to date the sanctions input behind a verdict, or to tell a clear OFAC flag from an unloaded list. Not for whether one address is listed: get_address_compliance (the flag) or get_address_risk (the tier). Not for indexer freshness: get_sync_status. No parameters; one answer covers every chain. Light read, never waits for a slot. No auth; 1200 requests/min shared by all tools. Verify against the official SDN list before acting on it; not legal advice.get_sync_statusIndexer freshness for one chain: freshness_seconds (the age of the newest indexed transfer; null when it could not be read for this answer), the indexer's head and finalized blocks, its safe block and its lag in blocks (lag_blocks = head_block - last_indexed_block). Use it before trusting how recent an address answer is, or to tell an empty feed from a stalled indexer. Not for how fresh the OFAC list is: get_sanctions_status. Every address verdict already carries freshness_seconds, so call this only for the block numbers or for a chain you have not asked about yet. On Solana (chain -1) safe_block is the finalized slot, and lag_blocks is near 0 by construction and never negative, so it is not a freshness signal there: read freshness_seconds. On the EVM chains and Tron a negative lag_blocks means the node's head went back. chain is the only parameter; omit it for Base. Light read, never waits for a slot. No auth; 1200 requests/min shared by all tools.get_wallet_graph_walkBounded walk over the indexed settlement graph of one stablecoin from one wallet on one chain: payer<->recipient hops with value-weighted scores, entity-aware node keys, a stop at known services and sanctioned-node markers. Use it to explain who an address settles with and through which hops. Not for a verdict: get_address_risk. Not for the taint class or haircut: get_address_exposure. Not for a flat list of transfers with tx hashes: get_recent_transactions. token is required and must be a stablecoin enabled on that chain (a refusal names them); hops=0 with stop_on_sanctioned=true is the cheapest check of the subject itself; subjects over the degree gate (~50k edge-rows) return hop 1 only with frontier_truncated=true. Heavy read: under load it answers busy or timeout — retry with backoff, a narrower window or a lower frontier_cap. No auth; 1200 requests/min shared by all tools. An explainability primitive, not a detector verdict, identity/control assertion, AML decision or legal advice. window_from present means the answer was built from that date, the edge-grain horizon, not from the start of the requested window; the default window all, 90d and 1y included (/v1/methodology edge_grain_horizon). When window_from is present, read the graph as covering that span only — do not treat the absence of a counterparty, a path or a sanctioned node as evidence about anything before that date. volume on nodes is the token's raw minor units (divide by 10^decimals); volume_usd6 is the same amount in USD with 6 decimals at peg 1. On Solana (chain -1) the answer carries coverage_status for the subject address only, never for its counterparties: pending — its history is still being filled, so an empty or small answer is not final; partial — filled to a documented bound. The walk shows a finished fill after the next Solana rollup pass (about 10 minutes), and never shows history older than window_from. This read never starts a fill, so pending can also mean none was asked for yet: one compliance read of the address asks for it. A Solana answer without coverage_status could not read it in time — treat it as pending. On Solana (chain -1) the edge grain of 2026-07-20..2026-09-14 is incomplete: those days hold part of their transfers or none, because their raw rows were offloaded before a fix reached production on 2026-09-17; they are not restored, and answers do not mark them (decision of 2026-09-17). Solana's grain is never trimmed, so there the horizon that window_from reports is not where retained data ends: once window_from is later than 2026-09-14 the answer holds none of those days. An answer that reaches them — window_from on or before 2026-09-14, or no window_from over a window that includes them — counts them as floors: at least this much, never the whole, and a counterparty, path or sanctioned node missing from those days is not evidence that there was none.fetchHTTP fetch with automatic authentication and payment handling. Makes the request, retries with SIGN-IN-WITH-X when the route exposes a SIWX challenge, and only pays if the route still returns 402. Returns response data and the final response headers, including raw payment receipt proof when supplied by the server, along with payment details (price, tx hash) if a payment was made.
For endpoints you haven't called before in this session, you MUST call check_endpoint_schema first to confirm the request body schema. Skipping this causes 400 errors from wrong field names.get_balanceGet your total USDC balance across all supported networks. Auto-creates the wallet on first use (~/.agentcash/wallet.json). Use this before paid API calls to confirm you have funds available.list_accountsList wallet accounts for each supported network. Returns the network, address, balance, and deposit link for every supported network so you can see where to fund the wallet. Auto-creates the wallet on first use (~/.agentcash/wallet.json). If onboardingCta is present, show its message to the user — it means they haven't onboarded yet and need to either visit the onboard link or deposit directly.check_endpoint_schemaGet the input/output schema and auth mode (paid or SIWX) for a single endpoint.
Call this to see exactly what fields the request body expects and what the response contains.
Returns the schema from the origin's OpenAPI spec. Optionally pass sample_input_body to probe the endpoint live (without payment) for an exact price quote — do this when pricing is dynamic (range-based or variable), or when you're unsure about the input schema. Treat auth mode as advisory: fetch handles both SIWX and paid routes.redeem_inviteRedeem an invite code for free USDC on Base. One-time use per code. Returns amount received and transaction hash. Use get_balance after to verify funds, or list_accounts if you need the per-network deposit links as well.discover_api_endpointsList available endpoints at an API origin. Returns endpoint URLs with descriptions of what each does and the auth mode for each (paid or SIWX). Works with any origin, not just the registered ones.
Call this when you need to see what routes are available at an origin — whether it's one of the registered origins or any other origin you've identified as useful. Treat the auth mode as guidance for what the route may require; fetch handles both SIWX and payment.
The response always indicates whether guidance is available. Guidance is documentation published by the API provider explaining how endpoints work together, edge cases, and usage tips. compact guidance is included automatically; set include_guidance=true to force-include full usage documentation when you need to compose two or more endpoints or need clarification on how the origin works.report_errorEMERGENCY ONLY. Report critical MCP tool bugs. Do NOT use for normal errors (balance, network, 4xx) — those are recoverable.update_settingsUpdate user settings (persisted to ~/.agentcash/settings.json). Currently supports maxAmount — the maximum USD amount allowed per fetch request. If a fetch response requests more than this, the payment is rejected. Returns the current settings after applying changes.get_settingsGet current user settings. Returns persisted values from ~/.agentcash/settings.json with defaults applied.bridgeBridge USDC between supported networks using the current wallet. Requires a source network, destination network, and amount. Use this when funds are on one supported network and the user needs them moved to another. Bridging is subject to fees.searchSearch for relevant paid API services by describing what you need in natural language. Returns the best matching origins with endpoint details and pricing. The top result includes the full input/output schema so you can call it immediately via fetch.
Only use this when you DON'T already know which registered origin to use. If the task clearly maps to a registered origin (e.g. people search → StableEnrich, image generation → StableStudio), skip search and go straight to discover_api_endpoints on that origin. Search is for discovering NEW or UNKNOWN capabilities outside the registered origins.
Set broad=true to widen the search to include newer, unvetted tools that may not have established trust. Use this if the default results don't cover what you need.sessions_closeClose an MPP `tempo:session` payment channel. Pass the channelId surfaced in a prior fetch's paymentInfo together with the same URL you originally fetched. Signs a close credential with the on-chain settled cumulative amount and POSTs it to the server, returning the on-chain settlement transaction hash when available. Use this when you want to finalize a channel rather than leaving it open for the server to settle on its own schedule.Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
