"Email" matching MCP servers:

Enables AI agents to run domain-intelligence investigations through six free tools: sanctions screening, IP geolocation with VPN/Tor detection, email validation with breach status, company profiling, WHOIS and email-security scoring, and a single-call domain dossier.

Enables AI agents to query RankFabrik's four public data APIs—YouTube captions/transcription, places, jobs, and email verification—through thin MCP tools using a single federated API key.

Enables free breach-exposure lookup by email address, revealing data breaches, exposed data classes, and risk scores without requiring an API key.

Enables AI agents and MCP clients to retrieve company profiles, hiring signals, YC companies, Wikidata enrichment, email validation, OpenStreetMap places, market quotes, and remote jobs via eight tools backed by the user's own Apify account.

Enables MCP clients to look up data breaches and leaked passwords, search NVD CVEs and the CISA KEV catalogue, and generate passive attack-surface reports for a domain covering security headers, TLS, email/DNS security, and CT-log subdomains. All checks are read-only and passive, using only public third-party data sources.

Official parseAPI MCP server providing IP/place data, email/phone/domain validation, weather, currency, timezone, and holiday lookups as tools for AI agents.

MCP server (stdio, MIT) with five tools that run locally with no API key: offline IBAN validation, disposable-email and MX check, DNS lookup with SPF and DMARC, ECB euro exchange rates, and package vulnerability lookup for npm and PyPI. A bridge in the same repo connects to the hosted Ambolt server with 37 tools, including company registry lookup, EU and UK tenders and Solana swap quotes.

Provides AI agents with 22 data tools across 9 domains, including IP geolocation, email risk scoring, postal codes, countries, timezones, user-agent parsing, cryptographic hashing, Bible search, and QR code generation.

Company data for AI agents, paid per call in USDC on Base. Returns every third-party vendor a company can be proven to use — CRM, email, analytics, cloud, HR, payments — each with the DNS record or script that proves it. No signup, no API key.

Enables B2B lead intelligence through seven tools for company lookup, domain enrichment, person search, email finding, and startup discovery, accessible via MCP for AI agents.

A Model Context Protocol (MCP) server that exposes 23 free APIs (Steam, WHOIS, email, IP geolocation, currency, stocks, QR codes, and more) for use by AI assistants like Claude and Cursor.
