"smart" matching MCP servers:

Pay-per-call API that verifies whether a domain belongs to a real business. Returns a verdict (real/likely_real/uncertain/likely_fake/fake), a 0-100 score, and signals (WHOIS via RDAP, SSL via Certificate Transparency, homepage LLM judgment, contacts, social) — for KYB, vendor screening, fraud checks, and lead qualification.

An MCP server that statically audits Solidity smart contracts for common vulnerabilities like reentrancy and access control, enabling developers to identify and fix security issues via natural language.

Enables MCP-compatible AI clients to safely control Home Assistant devices and query MQTT sensors through natural language, using allowlist-guarded actions and pre-defined automations.

Enables AI agents to track, calibrate, secure, and audit Milwaukee M18 FUEL ONE-KEY power tools through BLE proximity, geofencing, torque profiles, remote lockout, and fleet telematics.

Quick-scan a smart contract for rug, honeypot, or centralization risk before sending funds. It combines verified source, live on-chain state, and heuristic Solidity analysis to return a SAFE/CAUTION/HIGH-RISK verdict.

Enables Claude to check and control Kwikset Halo-family smart locks, including listing locks, getting status, and locking or unlocking doors.

MCP server for SimpliSafe home security. Enables checking system status, sensors, events, arming/disarming, and controlling smart locks.

Audits Ethereum/Solidity smart contracts using the Cysic Minimax model, providing automated vulnerability detection, gas optimization suggestions, and markdown report generation.

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.

Provides access to ODEI's constitutional knowledge graph, AI safety guardrails, and EVM smart contract auditing tools. It enables users to query structured domain nodes, validate agent actions, and perform security audits directly through an MCP client.

AI-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.

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.

An MCP server that detects potential honeypot tokens on Ethereum, BNB Smart Chain (BSC), and Base.

Enables an LLM to author, validate, and test Wirefilter WAF and Smart Firewall rules using live schema and real CVE exploit templates.

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

Enables AI assistants to interact with Rhombus physical security systems, providing access to smart cameras, access control, IoT sensors, and alarm monitoring through the Rhombus API.

Enables AI agents and security researchers to query a curated knowledge base of 1,032 verified smart contract vulnerability findings from Sherlock audit contests, including acceptance rates and examples per vulnerability pattern.

Enables AI agents to inspect and operate multiple Kubernetes clusters through natural language, providing multi-cluster diagnostics, RBAC analysis, security checks, and app-centric deployment with GitOps and smart workload placement.

Enables an AI agent to search a curator-signed catalog of smart contracts, build transaction plans with per-call trust tiers, and simulate them before a human reviews and signs locally with their own wallet. The server never holds a private key, refusing only calls whose deployed code no longer matches the signed codehash.

MCP server for controlling Nuki Smart Locks via Home Assistant, enabling lock/unlock, intercom buzzing, and battery checks.
