About Precisely MCP Server
Fuse the Precisely geospatial intelligence network directly into your AI workflows, enabling your agents to accurately pinpoint addresses globally, extract demographics, and evaluate location-based risks with unparalleled precision.
LangChain's ecosystem of 500+ components combines seamlessly with Precisely through native MCP adapters. Connect 10 tools via the Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures — with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- Geocoding & Autocompletion — Supply partial strings and tell the AI to resolve absolute Coordinates globally (
geocode_address,autocomplete_address) - Risk Assessment — Submit coordinates to instantly read FEMA flood zones or comparative crime metrics for that property (
enrich_flood_risk,enrich_crime_risk) - Tax Boundaries — Ask the AI to parse the exact Local Sales Tax jurisdiction applying strictly to that rooftop coordinate (
get_local_tax) - Deep Enrichment — Convert standard US Addresses into comprehensive property records including square footage and household socioeconomic segments
The Precisely MCP Server exposes 10 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Precisely + LangChain Use Cases
Practical scenarios where LangChain combined with the Precisely MCP Server delivers measurable value.
RAG with live data: combine Precisely tool results with vector store retrievals for answers grounded in both real-time and historical data
Autonomous research agents: LangChain agents query Precisely, synthesize findings, and generate comprehensive research reports
Multi-tool orchestration: chain Precisely tools with web scrapers, databases, and calculators in a single agent run
Production monitoring: use LangSmith to trace every Precisely tool call, measure latency, and optimize your agent's performance
Precisely MCP Tools for LangChain (10)
These 10 tools become available when you connect Precisely to LangChain via MCP:
autocomplete_address
Returns up to 10 candidate addresses ranked by relevance. Designed for keystroke-by-keystroke usage in address input forms. Provide real-time address suggestions as users type using the Precisely Typeahead Autocomplete API, drawing from a comprehensive global address database to accelerate form completion and reduce entry errors
enrich_crime_risk
Returns crime indices normalized to a national average of 100 — values above 100 indicate higher-than-average risk. Assess the crime risk index for a specific location using the Precisely Risks API, returning normalized risk scores across categories like burglary, assault, vehicle theft, and overall crime relative to national averages
enrich_demographics
Returns rich socio-economic profiles for the census block or postal zone containing the coordinates. Retrieve detailed demographic segmentation data for a geographic coordinate using the Precisely Demographics API, including household income brackets, population density, education levels, age distribution, and consumer spending patterns
enrich_flood_risk
Returns flood zone classification (A, AE, X, V), base flood elevation, and risk index. Primarily covers US territories with FEMA data. Evaluate flood risk exposure for a specific location using the Precisely Environmental Risks API, returning FEMA flood zone designations, proximity to water bodies, elevation data, and flood risk scores
geocode_address
precisely.com. The API returns a ranked list of candidates with latitude, longitude, precision code, and match confidence. Always pass the most complete address string available to maximize match quality. The response includes PrecisionCode indicating match depth (S8 = rooftop, S5 = street-level). Forward-geocode a full or partial address string into geographic coordinates using the Precisely Geocoding API v1, which resolves against a world-class global address reference database covering 250+ countries and territories
get_local_tax
Returns the combined tax rate and individual components (state, county, city, special district). Determine the applicable sales tax rate and tax jurisdiction for a geographic location using the Precisely Local Tax API, resolving complex overlapping US tax jurisdictions down to the rooftop level
get_property_info
Returns a rich property record sourced from county assessor databases. Coverage is US-only. Retrieve comprehensive property attribute data for a US address using the Precisely Property API v2, including lot size, building square footage, year built, number of bedrooms/bathrooms, assessed value, and ownership information
get_timezone
Returns the IANA timezone identifier (e.g. America/New_York), current UTC offset, and DST status. Resolve the timezone and current UTC offset for any geographic coordinate using the Precisely Timezone API, accounting for daylight saving time transitions and political boundary changes
reverse_geocode
Note the parameter order: x = longitude, y = latitude. Returns the closest matching address with full components (street, city, state, postal code, country). Convert geographic coordinates (latitude/longitude) back into a structured postal address using the Precisely Reverse Geocoding API, resolving the nearest rooftop-level address from the global reference database
verify_address
Returns a verified, standardized address with a verification status indicating if the address is deliverable, if components were corrected, or if the address is invalid. Validate and standardize a postal address against authoritative reference datasets using the Precisely Address Verification API, returning USPS/Royal Mail/local postal authority standardized formatting and deliverability status
Example Prompts for Precisely in LangChain
Ready-to-use prompts you can give your LangChain agent to start working with Precisely immediately.
"What is the exact sales tax for an e-commerce order delivered to '1 Market St, San Francisco, CA'?"
"Check the crime risk around the latitude 40.7128 and longitude -74.0060 relative to the national average."
"Can you verify if '350 5th Ave New York 10118' is a real deliverable address? If yes, give me its timezone."
