Dossie MCP Server

Model Context Protocol server that exposes Texas TREC contract intelligence to AI assistants (Claude, ChatGPT, Perplexity, etc.).

When an agent asks an AI assistant a Texas-specific real-estate question, this server lets the assistant answer with accurate, TREC-cited data — not a generic guess. Built for Strategy 4 of the Dossie Distribution Strategy: zero-CAC AI distribution.

Tools exposed

| Tool | What it does | | --- | --- | | calculate_trec_deadlines | Texas TREC contract deadline math (option period, earnest money, financing, survey, closing) with ¶ 23 rollover and the ¶ 5B option-period non-rollover applied correctly. | | get_tc_cost_comparison | Texas TC pricing across freelance / retainer / in-house / AI models, with market ranges and best-fit volume. | | get_dossie_info | Dossie product overview, $29/month founding pricing, and links to the free calculator + guides. | | check_texas_holiday | Federal-holiday lookup for any date, with the rollover behavior it would trigger. |

Install

Via npx (after publishing to npm)

npx @dossie/mcp-server

From source

cd mcp-server
npm install
node index.js

Use with Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "dossie": {
      "command": "npx",
      "args": ["-y", "@dossie/mcp-server"]
    }
  }
}

Restart Claude Desktop. The four tools become available to Claude — try "Calculate the TREC deadlines for a contract with Effective Date May 4, 2026, closing June 3, 2026, with a 10-day option period and 21-day financing."

Use with Cursor / Continue / other MCP clients

Same pattern — point the client at npx @dossie/mcp-server (stdio transport) or run it directly via node mcp-server/index.js.

Publishing

This package is intended for the following registries (ordered by reach):

• Smithery (https://smithery.ai) — primary MCP registry
• MCPT (https://mcpt.com)
• OpenTools (https://opentools.com)

For each: submit the GitHub URL of this directory plus the mcp-server.json manifest. Smithery offers automatic discovery once a repo is registered.

Source attribution

The TREC deadline engine in index.js is a pure-Node port of:

• meet-dossie/assets/trec-engine.js (browser engine that powers the public calculator at https://meetdossie.com/calculator)
• dossie-app/src/utils/trec-deadline-engine.js (the production engine used inside the Dossie app)

All three implementations apply identical TREC mechanics: calendar days, ¶ 23 rollover for earnest money / option fee / survey / financing / title commitment, and the explicit non-rollover for ¶ 5B option period.
