## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-20 (score 68)

First indexed and scored.

## MCP tools (10)

### `agent_address` (~53 tokens)

Return the agent's currently derived on-chain addresses. This tool is read-only and never authorizes or signs a payment. Production value movement is available only through the verified SDK v2 settlement executor after trusted deployment pins are released.

Output parameters:

- `casper` (string): Casper identity derived from the same seed. Read-only in this MCP RC; no payment signing tool is exposed.
- `evm` (string): EVM address used across EVM networks (Polygon, Base, Arbitrum, Optimism, BNB, Unichain, Avalanche, Robinhood, etc.)
- `note` (string)
- `solana` (string): Solana base58 address

### `agent_reload` (~43 tokens)

Reload the configured local wallet files after init or a file update, without starting a new conversation. Returns public addresses only. Shell environment changes still require reconnecting the MCP process.

### `agent_quota` (~113 tokens)

How many prepaid requests this agent has left, per service. Lists the agent's active quota batches (merchant, resource, used, remaining, expiry). Read-only; never spends, pays, or signs anything. Ask it things like: how many calls do I have left at mrch_x?

Input parameters:

- `include_exhausted` (boolean): Also list batches with 0 remaining (still retained, not yet expired).
- `merchant_id` (string): Optional mrch_… filter — only batches bought from this service.

### `agent_history` (~141 tokens)

Read an agent's payment history by EVM address, public passport identifier, or both. Defaults to the current wallet. Transactions are indexed AiFinPay Polygon settlements, not arbitrary wallet transfers. Receipts include retained prepaid batches and test payments. Never pass a seed, private key or API secret as a passport.

Input parameters:

- `address` (string)
- `limit` (integer)
- `network` (string): Exact passport wallet network; indexed transactions currently support polygon only
- `offset` (integer)
- `passport` (string): Public @username, AIFP-… number or aifp_agent_… identifier
- `source` (string)

### `agent_passport_resolve` (~70 tokens)

Resolve an AiFinPay Agent Passport by @username, permanent AIFP number, or immutable agent id. Returns verified public wallet bindings only. Resolution never authorizes a payment.

Input parameters:

- `identifier` (string, required): @username, AIFP-#########, or aifp_agent_* id

### `settlement_routes` (~83 tokens)

Read AiFinPay's currently runtime-verified v1.3 settlement routes. AIFP-1 is merchant monetisation (99% merchant / 1% AiFinPay / 0% creator). AIFP-2/x402 is 100% provider / 0% AiFinPay / 0% creator.

Input parameters:

- `route_class` (string)

### `settlement_invoice` (~149 tokens)

Build and validate a NON-SIGNING v1.3 settlement invoice for EVM chains. This tool never moves funds. Use the published @aifinpay/agent v2 settlement executor to verify bytecode/profile and sign it.

Input parameters:

- `asset` (string, required): Native symbol, USDC, or USDT if the route advertises it.
- `chain` (string, required)
- `gross_amount` (string, required): Gross payer amount in base units.
- `merchant_wallet` (string, required): Merchant/provider EVM wallet (0x...).
- `order_id` (string, required)
- `route_class` (string, required)
- `valid_until` (integer): Optional Unix seconds, max 20 minutes ahead.

### `settlement_solana` (~162 tokens)

Build and validate a NON-SIGNING Solana settlement invoice. This tool never moves funds. Uses the AiFinPay Solana B2B split program (Anchor). Use the published @aifinpay/agent v2 settlement executor to sign and submit.

Input parameters:

- `asset` (string, required): SOL (native) or USDC (SPL token).
- `chain` (string, required)
- `gross_amount` (string, required): Gross payer amount in base units (lamports for SOL, 6 decimals for USDC).
- `merchant_wallet` (string, required): Merchant/provider Solana base58 public key.
- `order_id` (string, required)
- `route_class` (string, required)
- `valid_until` (integer): Optional Unix seconds, max 20 minutes ahead.

### `settlement_casper` (~153 tokens)

Build and validate a NON-SIGNING Casper settlement invoice. This tool never moves funds. Casper uses Wasm smart contracts and deploys (not EVM transactions). Use the published @aifinpay/agent v2 settlement executor to sign and submit.

Input parameters:

- `asset` (string, required): CSPR (native Casper token).
- `chain` (string, required)
- `gross_amount` (string, required): Gross payer amount in motes (10^-8 CSPR).
- `merchant_wallet` (string, required): Merchant/provider Casper account hex (account-hash-...).
- `order_id` (string, required)
- `route_class` (string, required)
- `valid_until` (integer): Optional Unix seconds, max 20 minutes ahead.

### `deployment_info` (~115 tokens)

Get AiFinPay deployment details across EVM, Solana, and Casper — addresses, stablecoins, program IDs, and settlement status. Filter by ecosystem (evm/solana/casper), environment (prod/dev), or network name.

Input parameters:

- `ecosystem` (string): Filter by ecosystem. Omit for all.
- `environment` (string): Filter by environment. Omit for all.
- `network` (string): Filter by exact network name (e.g. 'optimism', 'mainnet', 'casper-test').

## Common questions

### What is the AiFinPay MCP server?

AiFinPay is an MCP server listed in the public MCP registry as io.github.daochild/aifinpay. Pay for any HTTP API in stablecoins on Polygon and Solana with one MCP call. This page covers its npm package (@aifinpay/mcp).

### Is the AiFinPay MCP server safe to use?

AiFinPay scores 68 out of 100 on VerifyMCP. We recorded 2 known advisories against it as of 20 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the AiFinPay MCP server expose?

AiFinPay exposes 10 tools: agent_address, agent_reload, agent_quota, agent_history, agent_passport_resolve, and 5 more. Their descriptions and schemas cost roughly 1,082 tokens of context every time the server is loaded.

### Is the AiFinPay MCP server still maintained?

AiFinPay is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the AiFinPay MCP server under?

AiFinPay declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
