Address Validator API
Normalize and validate customer shipping addresses inside your agent while building checkout, CRM, or fulfillment features.
Overview
Address Validator is a MCP server for the Build phase that parses, validates, and normalizes postal addresses with country detection via a remote SSE x402 API.
What is this MCP server?
- Parse, validate, and normalize postal addresses with country detection
- Remote MCP over SSE at address-validator.api.klymax402.com/mcp
- x402-paid API model for metered agent calls
- Version 1.1.0 Address Validator API from GitHub address-validator-x402
- Format verification suitable for ecommerce and logistics agent workflows
- Server version 1.1.0
- Remote SSE endpoint https://address-validator.api.klymax402.com/mcp
- x402 micropayment model for API access
What problem does it solve?
Agents and prototypes accept invalid or ambiguous addresses because per-country validation rules are tedious to embed in every form or script.
Who is it for?
Indie ecommerce, SaaS signup, and fulfillment automations where the agent should fix or flag addresses before data hits the database.
Skip if: Teams that need only client-side regex for a single domestic market with no agent in the loop, or builders avoiding x402 metered APIs.
What do I get? / Deliverables
Your agent returns normalized, country-aware address validation results through a single remote MCP call during feature work.
- Validated and normalized address structures from free-text input
- Country detection and format verification responses for agent-driven code
- Integration with metered x402 API billing for production agent usage
Recommended MCP Servers
Journey fit
Address validation is a build-time integration when forms, APIs, and agent tools need correct postal data before you ship. Integrations fits because the server is a remote SSE MCP endpoint (x402) that parses and normalizes addresses—not a standalone UX skill.
How it compares
Remote validation MCP over x402, not a local open-source address library skill.
