Operator pattern detected

This publisher (tairon-ai) operates 13 MCPs in our catalog. Median trust score: 56.

Computed 2026-09-16

· median trust 56 ≤ 60
· 92% of MCPs are D or F
· wallet-grade env vars shared across MCPs: WALLET_PRIVATE_KEY (×8)
· 3 risk keywords appear in ≥2 of the operator's MCPs (top: "private key" ×7, "mnemonic" ×6, "seed phrase" ×2)

Operator-pattern signals come from machine analysis of every MCP under this publisher's GitHub org. They are factual aggregates — not accusations. Investigate the individual MCPs before drawing conclusions.

⚠️

Known vulnerabilities in dependencies: 15 high

Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.

✅

No credential exfiltration, no sensitive file access, no obfuscation

Static analysis found nothing flowing your secrets to unexpected places.

✅

Open source with a license and README

Anyone can audit the code, the license is declared, and the publisher documents what it does.

🔐

You'll be asked for 2 credentials: API_KEY, WALLET_PRIVATE_KEY

These are read from process.env at runtime. Make sure you trust where they’ll be sent.

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

create_wallet

Generate a new 0G Chain wallet with private key and mnemonic phrase. Creates an Ethereum-compatible wallet that can be used on 0G Chain for transactions, staking, and smart contract interactions. Returns address, private key, and 12-word mnemonic phrase.

get_balance

Check the balance of 0G native tokens for any wallet address. If no address is provided, checks the balance of the wallet configured in WALLET_ADDRESS environment variable. Returns balance in both 0G tokens and wei formats, along with explorer link.

send_native_token

Send 0G native tokens to another wallet address. Transfers tokens from the configured wallet (WALLET_PRIVATE_KEY) or specified private key. Automatically checks balance, estimates gas, and waits for confirmation. Returns transaction hash and explorer links.

stake_tokens

Stake 0G tokens to a validator to earn rewards. Accepts either validator consensus public key (96 hex chars) OR validator EVM address (40 hex chars, from explorer). Delegates tokens through the 0G Chain staking contract. Returns transaction hash, validator info, estimated rewards (APY ~12.5%), and s…

unstake_tokens

Unstake (undelegate) 0G tokens from a validator. Burns delegation shares and starts 21-day unbonding period. Tokens automatically sent to withdrawal address after unbonding. Requires withdrawal fee payment. Supports partial or full unstaking ("all"). Returns transaction hash, shares burned, approxim…

get_staking_info

Get detailed staking information and estimated rewards for a specific validator. Shows current stake (shares + tokens with accumulated rewards), validator commission, estimated APY (~12.5%), daily/monthly/yearly reward estimates, and share of validator stake. Read-only operation, no private key need…

get_validators_list

Get list of known 0G Chain validators. Returns validator names, addresses, and explorer links. Can optionally fetch detailed on-chain information (total staked, commission rates, withdrawal fees) for all validators. Read-only operation, no authentication needed. Useful for discovering validators to …

get_accumulated_rewards

Get accumulated rewards information for a delegator. Shows current stake value (which includes auto-compounded rewards), optional reward calculation if original stake provided, and future reward estimates. NOTE: 0G Chain automatically compounds rewards into stake - there is NO separate claim functio…

get_validator_info

Get comprehensive detailed information about a specific validator including staking metrics, commission rates, withdrawal fees, reward estimates, and performance calculations. Shows total staked, share ratios, APY estimates, and example reward calculations for different stake amounts (100 0G, 1000 0…

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

9/9 tools missing one or more hints — create_wallet (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_balance (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); send_native_token (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +6 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tests exist

No test files found

Add tests that exercise each declared tool.

Secrets not logged

1 secret value sent to console.log

Redact or omit secret values from log output.

Production dependencies are patched

0 critical, 15 high severity in production deps — @modelcontextprotocol/sdk@1.7.0 (high), @modelcontextprotocol/sdk@1.7.0 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail

The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.

// improvement guidance — verified publishers only

We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
