"address validation" matching MCP servers:

Enables AI assistants to validate and standardize US addresses using the official USPS Address Validation API with secure OAuth2 authentication.

Provides email validation and domain configuration auditing tools for AI assistants, enabling single address checks, bulk list cleaning, SPF verification, and full mail setup grading (A-F) with actionable fixes.

MCP server for Crypto APIs Address History product, enabling querying full blockchain address transaction history for synced addresses across EVM and UTXO blockchains.

Enables a language model to run four deterministic data checks it cannot argue with — column-contract validation with an explicit quarantine list, arithmetic reconciliation of opening/movements/closing, distinct entity counting against row counts, and duplicate detection returned for human review — each answering with structured findings and row/column locators. Failures come back as results with reasons, so the model reports exactly which rows and columns are broken rather than asserting the data is clean.

An MCP server for AddressPenny address validation that enables users to validate postal addresses, bulk-clean address lists, and extract addresses from unstructured text through Claude Desktop, Cursor, and other MCP-compatible agents.

Provides email, phone, and address validation using Byteplant's APIs. Enables real-time live validation in any MCP-compatible client.

Query recent blockchain address data (last 14 days) for EVM, UTXO, Solana, XRP, and Kaspa networks without requiring address sync.

MCP server for Crypto APIs Utils, enabling address validation, raw transaction decoding, and XRP X-Address encoding/decoding for UTXO, EVM, and XRP blockchains.

Enables address validation, geocoding, postcode lookup, and reverse geocoding in 240+ countries, including UK Royal Mail PAF data, through four tools for MCP-aware clients.

Email validation MCP server using MailboxValidator API to determine validity of an email address.

An MCP server that exposes ISO 20022 postal-address classification, assessment, and remediation tools for AI agents, enabling them to prepare debtor/creditor addresses for the November 2026 structured-address cutover.

Provides read-only, real-time access to TON blockchain data including wallet balances, token holdings, transactions, prices, NFTs, DNS resolution, and address validation, without requiring private keys.

MCP server that provides 31 tools for the DaData API, enabling address autocomplete, company lookup, bank details, phone/email/passport validation, car recognition, geocoding, and reference directory queries.

Enables offline Nano (XNO) address validation with checksum checks, wallet creation, account derivation, and message signing via MCP, with no network calls.

Enables AI-assisted Attribute-Based Access Control code validation and review, with batch processing and progress notifications for long-running operations.

MCP server for AI agents to interact with the Ninja/AnaNinja mobile API, enabling mobile-compatible auth, address management, retail/grocery product search, draft order validation, and checkout/payment flows.

Agent trust & data safety MCP: PII/secret redaction, email validation, sanctions screening, and OSV vulnerability checks for AI agents.

A stdio MCP server exposing a validate_emails tool that lets agents screen email lists without sending mail or probing SMTP, checking syntax, DNS/MX records, disposable domains, role accounts, free providers, typo suggestions, and SPF/DMARC. Each address comes back with a valid/risky/invalid/unknown verdict plus machine-readable reason codes so agents can clean leads and signups before outreach or import.

An MCP server that uses Xiaomi MiMo v2.5 multimodal model to provide image recognition capabilities (description, multi-image analysis, OCR, and image info validation) for text-only main models like deepseek-v4-flash, accepting local paths, URLs, file://, and base64 data inputs.
