Dilix MCP

The open-source MCP server for Dilix — the regulatory intelligence layer for real estate AI agents.

Add Dilix to any MCP-compatible AI agent in 30 seconds. Get zoning, permits, entitlement roadmaps, state legislation flags, and deal scoring for any US property — surfaced as 10 callable tools.

Heads up: This package is the open-source client. The Dilix API (data + intelligence) requires an API key — get one free at dilix.ai/api-keys.

Why Dilix exists

Real estate is one of the largest opaque asset classes in the world. Owners close on properties unaware of regulatory shifts that compress NOI. Flippers burn months of carry on permits that never land. Brokers waste deal cycles chasing entitlements that won't clear.

Dilix is the data layer that catches it all — every permit, zoning change, and bill across 16 cities and 11 states, going national. For humans, and the AI agents reshaping the industry.

This MCP package gives those agents direct access.

Install

npm install -g @dilix/mcp

Or run on demand without installing:

npx @dilix/mcp

Get an API key

Free tier: 100 calls/month. Sign up at dilix.ai/api-keys.

Set it as an environment variable:

export DILIX_API_KEY="your-key-here"

Wire it into Claude Desktop

Add to ~/.claude/claude_desktop_config.json (Mac) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "dilix": {
      "command": "npx",
      "args": ["-y", "@dilix/mcp"],
      "env": {
        "DILIX_API_KEY": "your-key-here"
      }
    }
  }
}

Restart Claude Desktop. The Dilix tools will appear in the MCP tool palette.

Wire it into Cursor / Continue / custom agents

Any MCP-compatible host. Spawn the binary with DILIX_API_KEY in the environment. Speaks standard MCP over stdio.

Available tools

| Tool | What it does | |------|--------------| | analyze_zoning | Zoning + HCD compliance + state-law flags for any address | | get_entitlement_roadmap | Full approval pathway with timelines, fees, risks | | lookup_property | Property records, valuation, sale history (US) | | find_opportunities | Scan a city for SB-9, SB-79, AB-2011, AB-130 candidates | | scan_portfolio | Bulk compliance + opportunity scan across up to 50 properties | | watch_parcel | Hourly autonomous monitoring with email alerts | | track_permit | Real-time permit status + status-change notifications | | analyze_deal | Full deal score: zoning + property + financials + verdict | | source_deals | Source candidate properties matching investment criteria | | get_market_rates | Live SOFR + 10Y Treasury for cap-rate underwriting |

Full schemas: docs/tools.md (coming soon — for now, MCP hosts will expose them automatically once connected).

Example: Claude analyzing a deal

User: Should I pursue 555 California St for a residential conversion?

Claude (with Dilix MCP):
  1. analyze_zoning(city="San Francisco", address="555 California St")
     → C-3-O zoning · Builder's Remedy active · AB-2011 eligible
  2. get_entitlement_roadmap(...)
     → Ministerial pathway · CEQA exempt · 6-9 mo timeline · $X est. fees
  3. lookup_property(address1="555 California St", address2="SF, CA 94104")
     → Built 1969 · 350K sqft · last sold 2018 · $X assessed

Verdict: Strong candidate. Pursue. Submit SB-330 vesting application
within 30 days to lock current rules.

Grounding — every tool returns reasoning + sources

Starting in v1.1.0, every Dilix MCP tool surfaces a structured envelope to the host model:

_reasoning — plain-English narrative the agent can quote verbatim to the user. Composed by Dilix from structured fields, not extrapolated. Eliminates the most common failure mode (host model invents a cap rate / code section / date that wasn't in the response).
_sources — citations the agent can surface as "Source: X" links. Includes provider, citation text, and a verifiable URL where available. Pulled from real authorities: ATTOM, DataSF, FEMA, HUD, NY Fed, FRED, Cal. Civ. Code, municipal codes, etc.
_caveats — soft warnings the agent should pass through (e.g. "no parcel-level zoning available for this address — answers are city-level only").
_schemaVersion — pin behavior across upgrades.

The MCP server splits these into separate content blocks so the host model receives the narrative as the primary text and citations as a structured second block. Agents that want the raw payload still get it as a JSON block.

Endpoints currently emitting the envelope: analyze_deal, analyze_zoning, get_entitlement_roadmap, lookup_property, market_rates, find_opportunities, scan_portfolio. Others fall back to the legacy single-block JSON response.

Configuration

| Env var | Required? | Default | Description | |---------|-----------|---------|-------------| | DILIX_API_KEY | Yes | — | Get from dilix.ai/api-keys | | DILIX_API_BASE | No | https://api.dilix.ai | Override for self-hosted or staging |

Pricing

The MCP client is free and open-source (MIT). The hosted Dilix API is usage-based:

Free tier: 100 calls/month
Pro: $49/month — 5,000 calls
Agentic: $499/month — 50,000 calls + portfolio monitoring + webhooks
Enterprise: custom — email [email protected]

See dilix.ai/pricing for the live tiers.

Why open source?

Same playbook as Anthropic, Vercel, Supabase, Resend: open the developer surface, charge for the data + infrastructure behind it.

We open-sourced the MCP client because:

Devs deserve to read the code that runs in their agent
The MCP spec is open (Anthropic, late 2024) — closing the client would be hypocritical
The client is just the "USB cable." Our actual value is the data + scoring + intelligence behind the API
