Paragon MLS
Fetch real estate listings from Paragon MLS APIs and analyze rental investment properties.
Quick Start
- Build and configure the MCP server once:
cd paragon-mls-mcp && npm install && npm run build
- Add to
mcporterconfig (or your MCP client config):
mcporter config add paragon-mls --command "node /home/umbrel/.openclaw/workspace/deal-analyst/paragon-mls-mcp/dist/index.js" --transport stdio
- Use the tools:
# Fetch all listings from a shared MLS link
mcporter call paragon-mls.fetch_listings mlsId="6d70b762-36a4-4ac0-bedd-d0dae2920867" systemId="globalmls"
# Fetch a single property by MLS number
mcporter call paragon-mls.fetch_property mlsNumber="201918514" systemId="globalmls"
# Analyze a deal with the spreadsheet-compatible Four-Square model
mcporter call paragon-mls.analyze_deal mlsNumbers="201918514" systemId="globalmls" holdingPeriodYears:5 downPaymentPct:0.25
# Analyze multiple properties with custom assumptions
mcporter call paragon-mls.analyze_deal mlsNumbers="201918514,202012345" systemId="globalmls" downPaymentPct:0.25 interestRate:0.065 monthlyInsurance:250 repairBudget:10000 landValue:35000
# Compare velocity banking strategies for a deal
mcporter call paragon-mls.vb_calc debtBalance:350000 interestRate:0.05 loanTermYears:30 monthlyIncome:8000 monthlyExpenses:4878.875681 extraPayment:1000
# Get raw JSON data
mcporter call paragon-mls.raw_listings mlsNumbers="201918514" systemId="globalmls"

Common Paragon MLS system IDs (the subdomain before .paragonrels.com):
| Region | System ID |
|---|---|

Check your local MLS website URL to find the correct system ID.
How It Works
The server calls Paragon's public CollabLink API endpoints:
- CreateGuid — generates a session GUID for API calls
- GetNotificationAppData — resolves a listing GUID into MLS numbers
- GetListingDetails — fetches property data for each MLS number
Property data is parsed from Paragon's nested JSON structure, handling both the "new" format (section-based DetailOptions) and "old" format (array-based).
Limitations
- Paragon's API is public but unofficial; it may change without notice
- Each MLS region may format listing data differently; the parser handles common formats but edge cases may require custom handling
- No authentication is required for public listing data
- The API returns data over HTTP (not HTTPS) for some regions
- Rate limiting may apply; the server processes listings sequentially with no intentional delay
