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 Security69
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability70
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 12604 tokens (~196/item across 64 items; 64 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 Management13
- Stability observed for 4 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
- Structured output schemas are declared (2% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 64 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 65 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

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
op_tx Optimism transaction ~203
Look up an Optimism transaction by hash: sender, recipient, value in ETH, nonce, gas limit, the 4-byte function selector and its block. Use to see what was sent or whether it exists; for success or failure and fees paid use op_receipt, for emitted events op_logs. Input is a 0x-prefixed 64-hex hash; an unknown hash returns 404, uncharged. Example: hash=0x721f3e9a996da49e2a8929bd2dd42e0f51344c11d7ca7bc3328fda349cdfae89. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

Current gas price on Polygon PoS (eth_gasPrice): gas price, base fee and suggested priority fee in gwei, plus what a plain POL transfer (21,000 gas) costs right now. Takes no input. Use before sending a transaction or to decide whether to wait; for the fee a past transaction actually paid use polygon_receipt. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.
| Name | Type | Req | Description |
|---|---|---|---|

No output schema declared.
No examples provided.
polygon_is_contract Polygon PoS contract check ~174
Check whether a 0x address on Polygon PoS is a smart contract or a plain wallet: bytecode size, and whether it is an EIP-1167 minimal proxy and which implementation it points to. Use before sending funds or approving a spender; for a fuller risk verdict use check_counterparty. A malformed address is rejected with 400, uncharged. Example: address=0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | 0x address |
No output schema declared.
No examples provided.
polygon_logs Polygon PoS recent event logs ~223
Recent contract event logs on Polygon PoS (eth_getLogs): the events a contract emitted over the last N blocks (1-1,000, default 50), optionally filtered by topic0 (the 0x 32-byte event signature hash). Returns up to 100 logs with block, transaction hash and topics. Use to watch transfers or contract events; for one transaction's outcome use polygon_receipt. Example: address=0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | 0x contract address |
| blocks | integer | – | How many recent blocks to scan (1-1000, default 50) |
| topic0 | string | – | Optional 0x event signature hash to filter by |
No output schema declared.
No examples provided.
polygon_nonce Polygon PoS account nonce ~160
Read the transaction count (nonce) of a 0x address on Polygon PoS, both confirmed and including pending transactions. Use to build the next transaction or to tell whether an address has ever sent anything; for its balance use polygon_balance. A malformed address is rejected with 400, uncharged. Example: address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | 0x address |
No output schema declared.
No examples provided.
polygon_receipt Polygon PoS transaction receipt ~202
Transaction receipt on Polygon PoS (eth_getTransactionReceipt): success or reverted, gas used, effective gas price, fee paid in POL, number of event logs and any contract created. Use to confirm a payment or call went through; for sender, value and calldata use polygon_tx. Input is a 0x-prefixed 64-hex hash; a pending or unknown hash returns 404, uncharged. Example: hash=0x23e86c30c46638b2e9798692fe89327a66aa8569a5d4a566125f655aeb8f80c7. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.
| Name | Type | Req | Description |
|---|---|---|---|
| hash | string | yes | 0x-prefixed transaction hash (64 hex characters) |
No output schema declared.
No examples provided.
polygon_token_balance Polygon PoS ERC-20 balance ~204
ERC-20 token balance of a wallet on Polygon PoS (USDC, USDT, WETH or any token, via balanceOf): raw amount, decimals, symbol and the human-readable amount, live from the token contract. Use to check stablecoin or token holdings before a transfer or trade; for the native coin use polygon_balance. Both inputs are 0x addresses (40 hex characters); no contract returns 404 and a non-ERC-20 contract 422, both uncharged. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | 0x wallet address |
| token | string | yes | Token: a ticker such as USDC, USDT, WETH or DAI, or the 0x ERC-20 contract address |
No output schema declared.

polygon_token_info Polygon PoS ERC-20 token info ~207
Look up the name, symbol, decimals and total supply of an ERC-20 token contract on Polygon PoS, live from the contract. Use to identify an unknown token address or to format raw amounts; for a holder's balance use polygon_token_balance. Input is a ticker (USDC, WETH…) or the token's 0x contract address; an address that is not an ERC-20 contract returns 422, uncharged. Example: token=0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

polygon_tx Polygon PoS transaction ~204
Look up a Polygon PoS transaction by hash: sender, recipient, value in POL, nonce, gas limit, the 4-byte function selector and its block. Use to see what was sent or whether it exists; for success or failure and fees paid use polygon_receipt, for emitted events polygon_logs. Input is a 0x-prefixed 64-hex hash; an unknown hash returns 404, uncharged. Example: hash=0x23e86c30c46638b2e9798692fe89327a66aa8569a5d4a566125f655aeb8f80c7. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.
| Name | Type | Req | Description |
|---|---|---|---|
| hash | string | yes | 0x-prefixed transaction hash (64 hex characters) |

wallet Base wallet balances and account nonce snapshot ~222
Base only (all 5 chains: wallet_balances; USD values: wallet_portfolio). An address on Base: ETH and major token balances (USDC, WETH, cbBTC, DAI, USDbC, cbETH, AERO, EURC) plus up to 20 token addresses you pass, the account nonce, and whether it is an EOA, a contract or an EIP-7702 account. The nonce counts outgoing transactions only; not transfer or trading history. Use to check a counterparty's holdings. Example: address=0x4200000000000000000000000000000000000006. Price $0.005/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | Wallet or contract address on Base (0x...) |
| tokens | string | – | Optional comma-separated extra ERC-20 addresses to check (max 20) |

wallet_balances Wallet balance, USDC balance: native and USDC balances on 5 networks ~196
Read a wallet's native coin and USDC balances on Base, Ethereum, Arbitrum, Optimism and Polygon in one call, live from each network, plus the USDC total. Use to find where a wallet's funds are before a payment or bridge; for one token on one network use <chain>_token_balance, for all tokens on Base use wallet_portfolio. A network whose nodes do not answer is listed with an error instead of failing the call. Example: address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045. Price $0.005/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.
