Wraps the DealFlowPro REST API to run institutional grade multifamily real estate underwriting directly from Claude. Exposes four tools: analyze_deal for full cap rate, DSCR, cash on cash, IRR, and 10 year cashflow projections; score_deal for quick screening with a 0 to 100 DFP Score; reverse_calc to compute maximum offer price from your target returns; and market_data to check flood zones and neighborhood demographics for any address. Built for syndicators and operators who need to screen 2 to 200 unit deals without opening Excel. Requires a paid API key from dealflowpro.io starting at $1 per request or $79/month for 50 daily requests.
Analyze multifamily real estate deals from Claude Code, Cursor, Claude Desktop, or any MCP-compatible client. The first real estate underwriting tool in the MCP ecosystem.
DealFlowPro is an AI-powered multifamily deal analysis platform. This MCP server wraps the DealFlowPro REST API, giving AI agents access to institutional-grade underwriting calculations.
Ask Claude naturally and it calls the right tool:
| Tool | Description |
|---|---|
analyze_deal | Full deal analysis: cap rate, DSCR, cash-on-cash, IRR, DFP Score (0-100), max offer price, yearly cashflows |
score_deal | Quick screening: DFP Score + key metrics |
reverse_calc | Max offer price from target returns (cap rate, CoC, DSCR, IRR) |
market_data | Flood zone, neighborhood income vs state median, job growth for any address |
All four carry MCP 2025-06-18 annotations (title, readOnlyHint, destructiveHint, idempotentHint, openWorldHint). Every tool is read-only.
This repo doubles as a Claude Code / Cowork plugin. The plugin connects to the
remote server at https://dealflowpro.io/mcp rather than the npm package above,
which means:
list_my_deals, get_deal_analysis,
get_my_criteria, and portfolio_summary — your saved deals, buy-box
criteria, and pipeline, scoped to your account.DFP_API_KEY to export; you sign in to
your DealFlowPro account when the plugin connects.claude --plugin-dir /path/to/dealflowpro-mcp-server
Use the npm package below instead if you want a local stdio server, prefer API key auth, or are wiring DealFlowPro into a non-Claude MCP client.
DealFlowPro is built to slot into AI eval pipelines and production AI stacks. The MCP server (this package, plus the remote endpoint at https://dealflowpro.io/mcp) wraps the same engine as the REST API — schema-strict, idempotent, predictable.
Auth + scoping. Every tool call requires a Bearer API key. Calls are scoped to the account that issued the key — no cross-tenant access path. Per-tool audit lines land in your account's logs/mcp_tool_calls.log capturing tool name + flattened arg keys (not values) — usage is auditable without exposing deal contents.
Rate limits per tier.
| Tier | Daily limit | Monthly | Cost |
|---|---|---|---|
| Free | 5 requests, lifetime | — | free, no card |
| Pay-as-you-go | balance-based | per credits | $1/request |
| Essentials | 50 req/day | ~1,500 | $79/mo |
| Premium | 200 req/day | ~6,000 | $149/mo |
| Enterprise | 1,000 req/day | ~30,000 | $399/mo |
Rate limit headers (X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset) returned on every response. 429 responses include Retry-After.
Error codes. Stable, documented at dealflowpro.io/api/docs/#errors — all errors are JSON {success: false, error: {code, message}} shape. Codes: invalid_input (400), invalid_json (400), unauthorized (401), tier_required (403), method_not_allowed (405), payload_too_large (413), rate_limit_exceeded (429), internal_error (500).
Tool schemas. Each MCP tool has a schema-strict input definition. Call tools/list against the remote endpoint to get the canonical schemas at runtime; the REST OpenAPI spec covers the same shapes (the four MCP tools map 1:1 to the four REST endpoints).
Eval harness pattern. For benchmarking, the recommended pattern: maintain a fixture set of (deal payload → expected metrics) pairs, run each against score_deal (lowest cost, ~$0.01/call), assert metrics within tolerance. The endpoint is deterministic — same inputs produce the same outputs.
Data handling. Request payloads are processed in memory and not persisted to disk. TLS 1.2+ in transit. Anthropic API calls (when DealFlowPro internally uses Claude for document extraction) flow through DealFlowPro's zero-data-retention Anthropic workspace. Full posture: dealflowpro.io/security#api-mcp-data-handling.
You have two install paths — pick the one that matches your client.
Use this for claude.ai web (Custom Connectors), Claude Code with HTTP transport, or Claude API mcp_servers. The endpoint is https://dealflowpro.io/mcp (Streamable HTTP, MCP 2025-06-18).
claude.ai web / Claude Desktop: DealFlowPro is not in Anthropic's Connectors Directory, so add it as a custom connector — Customize → Connectors → "Add custom connector" → name it DealFlowPro, paste https://dealflowpro.io/mcp → Add → Connect → sign in to DealFlowPro → click Allow. OAuth handles auth automatically (no API key to manage). Then in a chat, click "+" → Connectors → toggle DealFlowPro on.
Add DealFlowPro to Claude → — opens the dialog with the name and URL pre-filled. You still review and confirm before anything is added.
Team / Enterprise plans: members cannot add custom connectors themselves. An organization Owner adds it once under Organization settings → Connectors → Add → Custom (type: Web), and each member then connects their own DealFlowPro account from Customize → Connectors.
Claude Code (HTTP):
claude mcp add dealflowpro \
--transport http \
--url https://dealflowpro.io/mcp \
--header "Authorization: Bearer dfp_sk_your_key_here"
Claude API:
POST https://api.anthropic.com/v1/messages

Use this anywhere you want the MCP server running locally instead of remote — or for a client that has no remote-URL path of its own. Claude Desktop supports both: remote via Settings → Connectors, or the local config below.
1. Get an API key. Visit dealflowpro.io/api to claim a free 5-request key (no card) or buy pay-as-you-go credits. Delivered by email.
2. Add to your client.
Claude Desktop — claude_desktop_config.json:
{
"mcpServers": {
"dealflowpro": {
"command": "npx",
"args": ["-y", "dealflowpro-mcp"],
"env": {
"DFP_API_KEY": "dfp_sk_your_key_here"
}
}
}
}
Claude Code:
claude mcp add dealflowpro -e DFP_API_KEY=dfp_sk_your_key_here -- npx -y dealflowpro-mcp
Just ask Claude about a deal. It automatically picks the right tool.
