"Troubleshooting JavaScript Code" matching MCP servers:

Gives Claude access to Alchemy blockchain APIs by loading all API specs at startup and providing two tools: search and execute. Enables querying NFTs, token balances, transactions, and more via natural language.

pay-per-call x402 API endpoints as MCP tools — web search, page-to-markdown, PDF extract, JSON repair/validate, crypto price, weather, IP geo, DNS, markdown lint + 20 agent-commerce aliases. Each tool proxies to vibes-coded.com and settles via x402 (USDC/Solana). Free-trial endpoints need no auth; paid ones need an x402 signature. Catalog is fetched live, so new endpoints appear automatically.

Free MCP server for real-time cryptocurrency data. Get token prices, market overview, top movers, historical charts, and detailed token info directly in Claude Code, Cursor, or any MCP-compatible AI tool. Powered by CoinGecko with 70+ token mappings and built-in caching.

Pay-per-use IBM Granite AI over MCP — chat, code, embeddings, analysis, and forecasting, billed in USDC on Solana. No IBM account required.

Open-source MCP server exposing the Agent402.Tools catalog: 500+ deterministic pay-per-call tools for AI agents, including browser rendering, web search, PDFs, OCR, LLM inference, code execution, live financial/crypto/macro data, SEC EDGAR, and wallet-keyed memory. Free via proof-of-work, or pay per call in USDC across ten chains via the x402 protocol. No API keys, no signups

AI consensus market oracle for crypto traders and autonomous agents. BUY/SELL/HOLD signals with 11-signal consensus (RSI, MACD, funding rate, Fear & Greed, congressional trading, Polymarket edges). Ed25519-signed. x402 micropayments on Base.

An MCP server that lets your AI coding agent (Claude Code, OpenClaw, Codex, Cursor, etc.) discover and pay on-chain agents registered on ERC-8004, using Coinbase's official x402 protocol. No smart account. No bundler. No relay. Just your EOA, an HTTPS request, and an automatic 402 → sign → retry flow.

Enables paying for Ordinal marketplace calls from your own wallet in Claude Code or Codex, with local signing and gasless settlements.

Provides AI agents with access to a wide range of market data, including short interest, insider trades, financials, and macro indicators, through 26 tools across 31 datasets.

Enables agents to explore, chart, rank and compare ERC-4626 vaults across chains and protocols by reading live subgraph data, and to inspect trader performance and copy-trading lineage on Cope Market. Every tool computes derived figures such as drawdowns, annualised returns and windowed P&L rankings rather than exposing raw GraphQL queries.

Enables Claude to query Binance Spot market data, account balances, and execute trades via natural language, with withdrawals disabled by default for security.

Provides Ethereum blockchain data tools via Etherscan's API, enabling users to check balances, view transactions, track token transfers, fetch contract ABIs and code, monitor gas prices, and resolve ENS names.

Enables AI agents to query the Radiant blockchain, manage Glyph tokens, resolve WAVE names, and securely build, sign, and broadcast transactions with private key support.

MCP server providing AI agents access to 38 pay-per-call APIs (LLM, image, code, audio, crypto, web, IPFS) via HTTP 402 micropayments in USDC/USDm.

A comprehensive developer utility MCP server that provides 23 tools including web search, currency conversion, crypto prices, QR code generation, JSON formatting, and more.

Provides tools for AI assistants to interact with the Ethereum blockchain through standard JSON-RPC methods, enabling queries for account balances, gas prices, and smart contract code.

Wraps the 0mod API Gateway to provide tools for web scraping, data redaction, code cleaning, domain checks, DEX pricing, sentiment analysis, OCR, embeddings, and summarization, with automatic handling of HTTP 402 micropayments.

Enables MCP-compatible AI agents to research and trade prediction markets on Polymarket and Kalshi, including market search, orderbooks, price history, positions, order routing, and on-chain builder-code attribution, plus overshoot and dispute-risk signals.

Connect any AI agent to Arcis Protocol DeFi vaults through natural language, enabling deposit, withdrawal, and status queries without SDK or code.
