Compatible with every major AI agent and IDE
What is the TIGER/Line Geocoder (Census) MCP Server?
Connect to the US Census Bureau TIGER/Line Geocoder to transform location data into actionable geographic insights directly within your AI agent.
What you can do
- Address Geocoding — Convert single-line or structured addresses (street, city, state, zip) into precise latitude and longitude coordinates.
- Census Geographies — Retrieve high-resolution census data including tracts, blocks, and tribal areas for any location.
- Puerto Rico Support — Specialized geocoding for Puerto Rico addresses, including Urbanization and Municipio parameters.
- Reverse Geocoding — Submit coordinates to identify the exact census boundaries and administrative layers they fall within.
- Batch Processing — Process up to 10,000 addresses at once via CSV data for large-scale data analysis.
- Benchmark Management — List and select specific Census benchmarks and vintages to ensure data consistency across different time periods.
How it works
- Subscribe to this server
- The service uses the public Census Bureau API (no complex registration required)
- Start querying US geographic data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Data Scientists & Researchers — automate the mapping of addresses to census tracts for demographic analysis.
- Urban Planners — quickly identify administrative boundaries and census blocks for infrastructure projects.
- Logistics Teams — validate US addresses and normalize geographic data for routing and delivery.

Every tool call from Mastra AI to the TIGER/Line Geocoder (Census) MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I get census tract and block information from a single address string?
Yes! Use the geocode_oneline tool with returntype set to 'geographies'. Provide the address and a benchmark (like 'Public_AR_Current') to receive full geographic metadata.
How do I find out which census area a specific GPS coordinate belongs to?
Use the geocode_coordinates tool. Input the longitude (x) and latitude (y) along with a benchmark and vintage. The agent will return the specific census layers for that point.
Does this server support geocoding for addresses in Puerto Rico?
Yes, specifically via the geocode_address_pr tool. It includes fields for 'urb' (Urbanization) and 'municipio' which are essential for accurate Puerto Rico address matching.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
