"A guide to developing Chrome extensions" matching MCP servers:

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

Generates MCP servers from smart contract ABIs, enabling Claude to interact with any Ethereum contract via natural language commands.

Search BotHire, the machine-to-machine marketplace where AI agents hire each other and pay in USDT/USDC (gasless, Base/Arbitrum/BNB/Solana): find skills and agents by capability and trust score, read live market demand and stats, and get a step-by-step guide to hire or get hired.

An MCP server that provides access to Stern, a philosophical AI mentor combining rationalist thinking with stoic philosophy to guide users through personalized mentorship and smart contract accountability on Solana.

Provides AI assistants with a comprehensive toolkit for developing, testing, and deploying smart contracts on the Agoric blockchain. It supports key Agoric features such as the Zoe contract framework, ERTP asset handling, and cross-chain orchestration patterns.

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.

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, HyperEVM, Robinhood Chain, Solana and Tron.

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.

Enables LLMs to interact with the AT Protocol ecosystem, including Bluesky, through natural language. Supports public data access without authentication and full write operations with authentication.

MCP server that enables AI signing agents to pre-flight transactions by checking ERC-7730 descriptor safety, explaining function semantics, and scanning contracts for danger primitives.

MCP server that builds unsigned Paraswap token swap transactions for self-custody wallets, holding no keys and signing nothing. It returns raw transaction data for a human to review and approve before execution.

Lets AI agents check whether an EVM wallet address carries an EIP-7702 delegation across eight chains (Ethereum, Base, BNB Chain, Arbitrum, OP, Polygon, Gnosis, Unichain) and learn how to obtain a deeper paid report with delegate bytecode heuristics and risk levels. Read-only, never touching private keys or seed phrases.

MCP server for OrcaTrace, a pay-per-call Polymarket intelligence feed for AI agents. It provides tools to track smart money, whale entries with calibration, market repricings, and digests across 42K prediction markets, with payments settled via x402 on Base.

Provides live cross-DEX market data on six EVM chains, including per-venue prices, liquidity, and gross spreads with optimal trade sizes. Enables AI agents to query real on-chain data for BSC, Polygon, Arbitrum, Base, Avalanche, and Optimism via MCP tools.

Provides AI agents with direct access to the Ray Group DeFi UX rubric, named patterns, and cognitive-bias glossary for grounded UX assessments of DeFi protocols.

Gives MCP-compatible LLM agents direct access to real-time MEV and DeFi data via Valorem's x402-paid API endpoints, with payments in USDC on Base mainnet.

WaxSeal MCP gives AI agents cryptographic identity — verify any WaxSeal fingerprint, check Ed25519 signatures, and gate irreversible actions with human-signed approval tokens before execution. It connects Claude Desktop, Cursor, and Windsurf to the WaxSeal trust network so agents can prove who authorized an action and reject tampered credentials in under a second.

Enables checking whether a crypto link is a phishing lookalike of a wallet, exchange or dapp by comparing it against official domains and flagging lookalike characters, typosquats, punycode and bait words, fully offline. An optional paid full check adds domain registration age, DNS, redirect tracing and a page scan for seed-phrase prompts and drainer code.

An MCP server that provides real-time web search to AI agents via a pay-per-search USDC microtransaction system.

Enables LLMs to compile and verify Tolk smart contract code for the TON blockchain.

Provides MCP tools to disassemble Kaspa scripts, estimate compute costs, explain txscript errors, and look up opcodes.

Enables read-only verification of Unlock Protocol lock membership on-chain, checking whether a wallet holds a valid key for a lock on supported networks.

Enables AI agents to find LayerZero OFT bridge routes by token address and build ready-to-sign cross-chain transactions across 14 EVM networks.

Enables AI agents to certify documents, prove agreements, and verify counterparty claims with on-chain receipts on Hedera Hashgraph. Provides tools for document certification, two-party attestation, and agent registration with zero-config setup.

Enables agents to mint Ashfields NFTs on Ethereum by burning 100,000 $ASH per token, check wallet and mint status, approve allowances, and trigger royalty distributions.

Run a Shopstr / NOSTR marketplace storefront from an AI agent — create and update stalls and products in both the NIP-15 dialect and the Shopstr-modern NIP-99 dialect, including the cache POST that makes Shopstr cards actually render.

Pre-trade safety for EVM, Solana and TRON: simulates a real buy and a real sell against live liquidity, so a honeypot shows as a sell that fails instead of a vendor score, and audits a wallet's standing approvals across the three chains. Python standard library only, no API key.

On-chain rug-pull & honeypot risk screen for ERC-20 tokens, providing a SAFE / CAUTION / HIGH-RISK verdict based on live public RPC reads.

Teaches AI coding agents how to reason correctly about MetaMask Embedded Wallets / Web3Auth architecture, SDK choice, key derivation, auth flows, and common integration pitfalls.

This MCP server enables AI agents to interact with Ripar's decentralized registries on Algorand, offering tools for searching agents, checking reputations, listing jobs, auditing settlements, and composing unsigned transactions for payments.
