Best Solidity MCP Servers
Solidity is a statically-typed, contract-oriented programming language designed for implementing smart contracts on blockchain platforms, particularly Ethereum.
Why this server?
Provides tools for generating, auditing, fixing, and compiling Solidity smart contracts for EVM-compatible blockchains, including security analysis with exploit proofs and gas estimation.
AlicenseAqualityCmaintenanceAI-powered smart contract forge with an 8-agent adversarial security audit system. Generate, audit, fix, and compile Solidity and Anchor/Rust contracts across 8 chains.743 npm1MITWhy this server?
Provides static analysis for Solidity smart contracts, including contract metadata, function signatures, inheritance, call relationships, security detectors, and source code extraction.

Slither MCP Serverofficial
AlicenseAqualityDmaintenanceEnables static analysis of Solidity smart contracts using Slither, including contract metadata, function details, inheritance, and security detectors through MCP tools.2396AGPL 3.0Why this server?
Maps Solidity codebases to identify important files and code structures, prioritizing them based on importance
AlicenseAqualityDmaintenanceA powerful tool designed to help, primarily LLMs, understand and navigate complex codebases. It functions both as a command-line application for on-demand analysis and as an MCP (Model Context Protocol) server, providing continuous repository mapping capabilities to other applications.

MIDL MCP Serverofficial
FlicenseAqualityDmaintenanceEnables AI assistants to interact with the MIDL blockchain, supporting smart contract deployment, balance queries, asset bridging, Bitcoin Rune management, and more through natural language.291-Why this server?
Enables static security analysis of Solidity smart contracts for vulnerabilities such as reentrancy, unsafe delegatecall, and timestamp dependency, covering SWC/CWE categories and providing audit results.
AlicenseAqualityCmaintenanceEnables 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.4MITWhy this server?
Enables automated analysis of Solidity smart contract source code to identify malicious patterns such as asymmetric taxes, hidden administrative functions, and fraudulent ownership renouncements.
AlicenseAqualityDmaintenanceSafety layer for autonomous DeFi agents. Scans contracts for exploit patterns, simulates transactions, blocks honeypots.411 npm1MITWhy this server?
Provides AST-aware code intelligence for Solidity codebases, including semantic search, dependency graphs, and refactoring analysis.
AlicenseAqualityBmaintenanceStandard coding agents waste 70% of context tokens re-reading raw files with shell grep. Synapse-MCP indexes your codebase into a sub-millisecond local AST graph—giving Claude Code, Cursor, and Windsurf exact caller trees, 60% lower token spend, and zero-hallucination refactoring.141MIT
