"Finding MCP Servers with F Security Grades" matching MCP servers:

Enables paid, per-request access to raw on-chain token security data (honeypot, taxes, holders, liquidity) on Arc mainnet via x402 payments, without scores or advice.

A cross-chain bridge security auditing toolkit that exposes tools for analyzing, fuzzing, and simulating bridge contracts via natural language, enabling users to detect vulnerabilities like centralization risks and replay attacks.

Enables AI coding agents to scan smart contracts and code for vulnerabilities, check against 12 famous-hack patterns, and return public security receipts directly in the IDE.

Enables interaction with Binance Smart Chain, including wallet management, token transfers, contract execution, PancakeSwap swaps, and four.meme token creation.

An MCP server that statically audits Solidity smart contracts for common vulnerabilities like reentrancy and access control, enabling developers to identify and fix security issues via natural language.

An autonomous AI agent that monitors Base chain DeFi protocols for security anomalies and alerts via MCP tools.

Zero-key on-chain intelligence for Base, Ethereum, and Solana. Instant bytecode decompilation, honeypot detection, EIP-1967 proxy resolution, calldata/revert decoding, and pre-flight transaction simulation. No API keys or wallet connection required.

PulseChain on-chain analytics for AI agents. 20 tools: token safety scores (0-100, A-F), honeypot detection, whale tracking, smart money feed, scam alerts, DEX volume, bridge stats, holder leagues. 11 free + 9 pro with API key.

Enables AI assistants and trading agents to run Solana memecoin safety checks, including grades, red flags, launch bundles, same-second sellers, rug-farm links, and wallet activity.

Rescues USDC, USDT and USDG from wallets with no gas. Agents check a wallet for stuck or frozen stablecoins, quote a send or a swap into the gas coin, collect the wallet signature and track the transfer. Base, Arbitrum, Ethereum, Polygon, Avalanche, BNB Chain, HyperEVM, Robinhood Chain, Solana and Tron.

Enables AI agents to make pay-as-you-go AI inference requests through x402 with automatic Solana USDC payments, no API keys or registration, while enforcing configurable spending limits.

MCP server for RugGuard, enabling AI agents to perform pre-trade rug checks on tokens, with paid tools for token scanning and pre-trade verification, and a free metrics resource.

An MCP server that gives autonomous coding agents deterministic, schema-validated tools for EVM smart contract development — security scanning, gas profiling, compiler diagnostics, and transaction simulation.

Non-custodial on-chain escrow + AI arbitration for agent-to-agent USDC payments on Base. Seven tools wrap a verified EscrowV1 contract — create, deliver, confirm, dispute, resolve — with read-only introspection if no wallet key is provided.

Enables AI agents to read and bid on a paid message slot on Solana, with enforced spend limits, dry-run proposals, and an append-only audit log for every write.

Agent-Level Transaction Safety Oracle. Before an AI agent signs a blockchain transaction, it returns a SAFE/UNSAFE verdict with a SENTINEL Score (AAA-D) and risk flags. Pay-per-call $0.005 USDC via x402 on Base.

Enables AI agents to discover and pay for x402-gated HTTP APIs, handling 402 Payment Required flows with local signing. Supports EVM and Solana with non-custodial wallet management.

Keyless crypto payments for AI agents. One MCP call turns any wallet address into a non-custodial crypto payment link or tip jar, no API key and no account, with funds settling straight to your wallet at a 0% platform fee (USDC/USDT, BTC, LTC, DASH, DOGE, ZCASH).

Screens the counterparty of an x402 payment before an agent pays it. One tool, screen_payment, checks address sanity, dynamic-payTo swaps, transport safety and your spend policy, then returns allow / review / block with the reasons — advisory only, and by default it runs with no key, no account and no network call.

Resolves a company name, registrable domain, or LEI to its GLEIF legal entity record — LEI, legal name, jurisdiction, entity status, and registration status — for $0.05 USDC on Base paid per call over x402, with no signup or API key. Includes a free, no-wallet preview of price and coverage plus hard per-call and per-session spend caps, while misses and ambiguous matches cost nothing.

Enables blockchain mempool analysis with a free tier for basic queries and a premium tier for deep analysis, gated by a server-side paywall.

MCP server for Pi Network that enables AI agents to query Pi chain data (balances, transactions) and verify user tokens, with optional payment sending that is off by default.

fomox402 broker + MCP server for last-bidder-wins games on Solana. Drop one URL into Claude / Cursor / Goose / Cline and the agent auto-registers a Privy-managed Solana wallet (faucet-funded with ~0.0024 SOL + $fomox402), bids via x402 micropayments, claims dividends, and plays autonomously. 14 tools wired up — register_agent, place_bid, claim_winnings, claim_dividend, list_games, get_me, etc. Str

Enables static security audit of Solidity smart contracts by analyzing source code or deployed bytecode for vulnerabilities, providing risk scores and detailed findings.

Enables LLM assistants like Claude to interact with Zaif cryptocurrency exchange through natural language, supporting market information retrieval, chart data, trading, and account management for BTC/JPY, ETH/JPY, and XYM/JPY pairs.

7-layer Solana safety oracle and security infrastructure for AI agents.

MCP server for local transaction signing across EVM, UTXO, Tron, and XRP blockchains, with no network calls or API keys required.

Enables AI agents to post a task with quality levels, have a frontier model hired and graded on BrainChain, and pay only when the delivered work passes, with automatic refunds otherwise.
