What is the Smarty MCP Server?
Connect your Smarty account to any AI agent and empower your team to sanitize raw address data, query ZIP codes, and format global street locations securely. Interact with powerful geospatial and mailing validation APIs through natural language without writing a single line of custom script.
What you can do
- Address Validation (USA/Intl) — Effortlessly clean and verify messy user inputs calling
validate_us_address, returning the Delivery Point Validation (DPV) - Text Extraction — Feed your AI unformatted text like emails or notes and run
extract_addressesto intelligently isolate real physical addresses - Autocompletion Tests — Interrogate the AI dynamically with partial street names using the
autocomplete_us_addressalgorithm - ZIP Code Checks — Validate specific 5-digit postal zones using
verify_zip_codeto retrieve associated municipal limits
How it works
- Subscribe to this server
- Enter your Smarty Auth ID and Auth Token
- Start using Claude, Cursor, or any MCP-compatible client to query your geospatial APIs directly
Stop manually typing test addresses into the Smarty sandbox or setting up Postman. Your AI agent can validate address inputs right inside your coding or chat interface.
Who is this for?
- E-Commerce Devs — test the viability of formatting algorithms by parsing complex address lines dynamically in your IDE
- Data Engineers — upload raw customer data lists to your AI and have it extract valid postal locations sequentially
- Logistics Teams — quickly verify delivery endpoints for complex multi-unit apartment addresses internally

Frequently asked questions
Can the AI find an address hidden inside a block of text automatically?
Yes! You can paste an entire email string or customer support note into your prompt and ask the AI: 'Extract any addresses mentioned in this text.' The agent triggers the extract_addresses engine to return the geolocated and sanitized address format purely.
How accurate is the address verification?
Smarty ensures the address is validated against official sources like the USPS using DPV (Delivery Point Validation) for US requests, guaranteeing a package can actually be delivered to the mapped coordinate. Your AI agent returns this rigorous underlying metadata.
Can I use the agent to fix my dataset dynamically without coding?
Yes. If you have 20 poorly formatted customer addresses, you can simply paste them in the prompt, asking your AI to 'Run each of these through Smarty and return a markdown table of the normalized addresses.' The agent handles the iteration loop for you via the tools.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
