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

Facilitates interaction with the Bitcoin network via the Model Context Protocol, enabling key generation, address validation, transaction decoding, and blockchain data retrieval.

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

Enables AI assistants to validate email addresses, track validation tasks, view per-address results and account analytics, and export cleaned email lists through the UChecker API.

Provides address validation and geocoding for 240+ countries, including UK Royal Mail PAF and US/Canada census enrichment. Enables batch validation, forward/reverse geocoding, UK postcode expansion, and automatic refunds for failed lookups.

Enables AI agents to manage global shipping operations, including rate comparison, shipment creation, label purchasing, tracking, pickup scheduling, address validation, billing, and analytics, via natural language.

Enables AI agents to look up Czech companies, VAT status, entity KYC snapshots, address standardization, and Czech identifier validation via official ARES data.

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.

MCP server that translates natural language commands into SCARA robot arm control instructions, featuring simulation mode, safety validation, and multiple transport modes (STDIO/HTTP/OAuth).

VAST validation MCP server that checks ad tags against IAB VAST specifications, returning structured JSON with rule IDs, XPath locations, and spec references.

Enables AI agents to generate JSON configurations for creating images and videos programmatically through the Jsoncut API, with support for layers, positioning, transitions, and validation.

Provides a validation suite for VAT, IBAN, email, geo lookup, and VIN decoding, with per-call pricing and optional x402 payment support.

Gives AI agents their own email address with inbound parsing, classification, extraction, and prompt injection screening, plus tools to manage mailboxes, send/receive emails, and handle draft approval workflows.
