## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-22.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 63/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 3705 tokens (~308/item across 12 items; 12 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 12 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (12)

### `check_my_balance` (~205 tokens)

Check my wallet balance

Free. Check how much USDC is left in your own wallet on Base, so you can tell your human before you run out. Returns the balance and whether it's below your threshold. Read-only: it moves nothing. Tollkit never holds anyone's funds or keys.

When to use: You pay for tools from a wallet and want to know if it's running low.
Use instead: wallet_balance for any wallet, chain or token.
Parameters: address: the wallet you pay from. network: base (default) or sepolia. low_below: your low-balance threshold in USDC, default 1.
Returns: the USDC balance and whether it's below low_below. Free.

Input parameters:

- `address` (string, required): Your wallet address (0x...). The address you pay from.
- `low_below` (number): USDC amount you consider low. Default 1.
- `network` (string): Default base. Use sepolia for test money.

### `wallet_balance` (~317 tokens)

Wallet balance

Check a wallet's balances on Base, Ethereum or Solana: native ETH or SOL, USDC (plus USDT on Ethereum and Solana), and any token contracts or SPL mints you list (up to 20), with symbols and decimals applied. Read live from the chain.

$0.002 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed).

When to use: You need what a wallet holds, in token amounts.
Use instead: wallet_portfolio for USD values and a total; check_my_balance (free) for your own USDC on Base.
Parameters: address is required. chain: base (default), ethereum or solana; the address format must match. tokens: up to 20 extra ERC-20 contracts or SPL mints to include.
Returns: native coin, USDC (USDT on Ethereum and Solana) and the tokens you listed, each with symbol, decimals and amount.

### `token_info` (~259 tokens)

Token info

Look up a token on Base, Ethereum (ERC-20 contract) or Solana (SPL mint): name, symbol, decimals and total supply, plus mint and freeze authority on Solana, read live from the chain. Use it to confirm what an address actually is before acting on it.

$0.002 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed).

When to use: You have a token address and need to know what it is before acting on it.
Use instead: token_check for safety warnings and liquidity; token_price for its price.

### `transaction_lookup` (~266 tokens)

Transaction lookup

Look up a transaction on Base, Ethereum or Solana: did it succeed, when, who sent it, the fee, and every token movement with symbols and amounts (ERC-20 transfers; on Solana, SOL and token balance changes per owner). Use it to confirm a payment actually landed.

$0.002 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed).

When to use: You have a transaction hash and need to know if it went through and what moved.
Parameters: hash: 0x hash on Base or Ethereum, base58 signature on Solana. chain: base (default), ethereum or solana; it must match the hash.

### `token_price` (~307 tokens)

Token price

Get a token's current USD price on Base, Ethereum or Solana, read from its deepest on-chain pool (Uniswap v3 against USDC or WETH; on Solana, Orca Whirlpools against USDC or SOL) rather than a price API. Returns the pool used, how much liquidity backs the price, and a flag when the pool is too thin to trust.

$0.001 USDC per call over x402. Failed calls cost nothing. Call without `payment` to get a quote. The first 3 calls a day through this tool server are free (no wallet needed).

Input parameters:

- `chain` (string): "base" (default), "ethereum" or "solana".
- `payment` (string): Base64 x402 payment payload. Omit it to receive a quote; sign that and call again.

### `token_check` (~300 tokens)

Token check

Check a token before buying, sending or accepting it, on Base, Ethereum or Solana: what it is, its USD price and liquidity, and plain warnings read from the chain (no pool, thin liquidity; on Base and Ethereum the contract's owner and whether it is upgradeable or can mint, pause, blacklist or set fees; on Solana an active mint or freeze authority).

Tollkit Crypto scores 69 out of 100 on VerifyMCP. 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 Tollkit Crypto MCP server expose?

Tollkit Crypto exposes 12 tools: check_my_balance, wallet_balance, token_info, transaction_lookup, token_price, and 7 more. Their descriptions and schemas cost roughly 3,525 tokens of context every time the server is loaded.

### Does the Tollkit Crypto MCP server require authentication?

No. We connected to Tollkit Crypto without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Tollkit Crypto MCP server still maintained?

Tollkit Crypto is still listed as active in the MCP registry. We last reached this channel on 22 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
