"How to execute tests on a frontend page and debug browser console issues" matching MCP servers:

Provides structured access to Solana Anchor error data, enabling AI coding agents to parse logs, debug transactions, and look up error codes.

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

Inspects and debugs Solana transactions, accounts, Anchor IDLs, errors, and PDAs from MCP-compatible clients.

On-chain delivery receipts for x402 AI-agent payments on Solana: anchors SHA-256 digests of delivered content to a PDA after settlement; buyers verify proof of delivery offline with zero trust in the seller. Live MCP endpoint + npm bridge.

Pay-per-call MCP server for on-chain blockchain data including wallet profiles, token metrics, protocol TVL, and gas prices.

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

MCP server for Chainlink Runtime Environment, enabling build, simulate, deploy, and manage CRE workflows from any MCP client.

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

Local MCP-to-browser signing bridge for EVM, Solana, and Sui, letting agents prepare and simulate transactions while users approve and sign in a browser wallet extension.

Let your AI assistant pay for web content in USDC (x402 on Base) within a budget you set. Inside the budget it pays on its own; above it you are asked to confirm. The wallet key stays on your computer. For claude.ai and ChatGPT there is a remote server (https://agent.p2flux.com/mcp) where you approve each payment in your own browser wallet.

OTrust issues cryptographic PDRs (Provenance Data Records) — proving a digital artifact existed at a specific time. $0.01 per proof. Blockchain-anchored. Publicly verifiable.

Decentralized Git with on-chain governance, bounties, and DAOs. Tools for repos, issues, PRs, labels, releases, bounties, and DAO proposals. Auto-wallet on first use, trust tiers, and approval mode for human-in-the-loop.

Blockchain JSON-RPC on 23 EVM chains for AI agents — Ethereum, Base, Arbitrum, plus young chains like Robinhood Chain, Plasma and Ink. Free reads with no key; heavy methods (eth_getLogs, trace, debug) via a free API key or x402 USDC pay-per-call.

MCP server for Bags on Solana. Reads token analytics, creator-fee data and trade quotes; executes swaps and fee claims only behind a token gate, a hard SOL spend cap, and a single-use confirmation token bound to the exact arguments. The first call to a write tool signs nothing — it returns a preview. 14 tools, 337 tests at 100% coverage enforced in CI, mainnet-only writes, npm provenance.

Enables Solidity developers and security auditors to decode EVM calldata, pinpoint revert locations in debug traces, calculate storage slot layouts, and scan contracts for reentrancy and Yul assembly issues.

Enables AI assistants to discover prediction markets, view real-time data, execute trades (market/limit orders), and manage portfolios on Polymarket.

An MCP server providing tools for Sui blockchain interaction, including wallet management and Move smart contract development. It enables users to build, test, and publish contracts, query on-chain objects, and execute transactions through Claude.

Hosted MCP server for AI agents on X1, Arc, Solana and Base (Streamable HTTP at https://apexfaucet.xyz/mcp, no API key). Token exit checks on eight chains (can you sell it again?), Arc launch feeds with sell tests, Arc yield vaults with real exit liquidity, Base token verdicts, a web page reader, and free X1 and Arc faucets claimed by signature. Paid tools are pay per call over x402 in USDC.

A Model Context Protocol server that enables AI agents to autonomously execute cross-chain trading operations on Paloma DEX across seven EVM chains including Ethereum, Arbitrum, and Polygon.

Enables agents to manage Grok Chain grants and execute payments through human-funded vaults and a relayer, without ever holding private keys.

Enables AI agents to read chain data, execute transactions, swap tokens, and manage wallets on Solana through 38 tools across 7 modules. Supports write operations with a private key and includes built-in prompts for common workflows.

A Model Context Protocol server that enables AI assistants and applications to interact with decentralized exchanges (DEXs), allowing users to get quotes for token swaps and execute swap transactions.

A Model Context Protocol server enabling AI assistants to create, buy, and sell tokens on the Pump.fun platform on Solana.

Provides access to the Zora Coins ecosystem on Base mainnet, enabling users to query coin data, explore markets, analyze profiles, and execute trades through a standardized interface.

A server that provides tools for interacting with MantraChain blockchain through the Model Context Protocol, allowing users to manage tokens, stake assets, query balances, and execute various blockchain operations.

Enables reading o1 Launchpad data on Base Mainnet, preparing Standard token launches and exact-input buys/sells, preparing direct ETH/ERC-20 transfers and creator fee claims, and routing transaction approval to a local browser wallet for signing and broadcasting.

Enables MCP hosts and agents to authenticate, sync and manage a Capital Book, create and monitor Financial Compass objectives, inspect health, timeline, vault and executions, prepare non-custodial vault deposit and withdraw steps, and fetch or execute restore plans on Robinhood Chain.

MCP server for gittr.space, a decentralized Git platform on Nostr, enabling AI agents to create repos, push code, manage issues/PRs, and work with Lightning bounties using Nostr identity.

A Model Context Protocol server that gives LLMs the ability to interact with Ethereum networks, manage wallets, query blockchain data, and execute smart contract operations through a standardized interface.

MCP server for cross-chain bridging, enabling AI agents to find routes, estimate costs, check risks, execute transfers, and track status across blockchains.
