"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.

Provides developer-focused documentation and tools for building applications on Amp, a high-performance blockchain ETL system. Includes guides, schemas, code examples, and troubleshooting resources for querying and transforming blockchain data.

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

Universal x402 buyer agent — discover, pay for, and call any x402 paid API endpoint from Claude Desktop, Cursor, or Claude Code with automatic USDC payment via AgentCash.

Pre-flight oracle for x402 endpoints — gives any MCP-aware agent (Claude Code, Cursor, Windsurf, Continue) tools to detect decoys, zombies, and price traps before paying. Wraps preflight, forensics, decoy-blacklist, and watch-subscription endpoints from x402station.io.

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

An MCP server for Klever blockchain smart contract development, providing contextual knowledge including code patterns, best practices, and runtime behavior.

Provides local access to Aztec documentation, examples, and source code via cloned repositories, with optional semantic search for enhanced querying.

Enables searching over 20,000+ smart contract audit findings from Solodit, with filters for severity, firm, tags, and more. Designed for use with AI coding agents like Claude Code and Codex CLI.

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.

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.

Enables any existing API to become a pay-per-call service for agents by issuing HTTP 402 payment requests and settling USDC payments via CDP, while exposing MCP tools that charge per call and support Bazaar discovery.

MCP server that gives AI assistants access to Midnight blockchain—search contracts, analyze code, and explore documentation.

Enables AI assistants to audit Solidity smart contracts for security vulnerabilities, fetch verified source code from block explorers, decode calldata, and estimate gas costs across major EVM networks.

Enables AI agents to fetch and independently verify on-chain data such as account balances and contract code hashes using Merkle proofs and ECDSA signatures, with x402 payment integration.

Enables AI assistants to help developers integrate gasless transactions on the Aptos blockchain by providing access to documentation, code snippets, and transaction cost estimation. It facilitates interaction with the SmoothSend SDK and API through MCP-compatible tools like Cursor and Claude.

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 AI assistants to retain persistent, searchable memory and versioned vaults, spawn and recall named agents with state and audit history, run automations, monitors, and deep research, and execute on-chain and web tasks across sessions. It can be installed alongside Claude Code, Cursor, Windsurf, Zed, Hermes, and other MCP clients, with vault and memory optionally run entirely on the user's machine.

Fetches verified EVM smart contract source code, scans for vulnerabilities, analyzes token holder distribution, and generates audit reports.
