MCP Server

The Demiton MCP server exposes your operational data as tools that any MCP-compatible AI client - including Claude - can call directly. Ask questions about project financials, workforce, site records, and institutional memory in natural language, with every response sourced from your connected data.

Available on every tier. What changes between tiers is the scope of data the MCP can read:

Tier	What the MCP can read
Public	AusTender, ABR, BOM, and CKAN open data
Insights	Public data + your uploaded contracts and estimating data
Connected	Public data + uploads + your live integrated systems (ERP, field ops, payroll, documents)

Every tool call is identity-bound and audited.

Tip

Not sure which tier you need? Try the Cross River Rail public preview - real contractor and weather data, no account required. When you’re ready to ask questions about your own contracts, sign up for Insights.

How do I connect Claude or ChatGPT to Demiton?

Connected tier

The MCP server is accessible at your deployment’s /mcp endpoint.

In Claude Desktop, add to your claude_desktop_config.json:

{
  "mcpServers": {
    "demiton": {
      "type": "http",
      "url": "https://YOUR_DEPLOYMENT_URL/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Your deployment URL and API key are available in HQ → API Keys.

Note

The MCP server uses Streamable HTTP transport. It is compatible with Claude Desktop, Claude Code, and any client that supports the MCP protocol over HTTP.

Insights tier

After signing up at demiton.io/insights, your MCP endpoint and API key are available in HQ → API Keys.

In Claude Desktop, add to your claude_desktop_config.json:

{
  "mcpServers": {
    "demiton": {
      "type": "http",
      "url": "https://YOUR_DEPLOYMENT_URL/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

On Insights, the MCP reads from the procurement classification index applied to your uploaded contracts. Upload data first at app.demiton.io - see Uploading Your Data.

Public tier

The public tier exposes read-only MCP access to AusTender, ABR, BOM, and CKAN open data. A free Demiton account is required - sign up at demiton.io.

In Claude Desktop, connect using mcp-remote (OAuth 2.1):

{
  "mcpServers": {
    "demiton": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://api.demiton.io/mcp"]
    }
  }
}

On first run, mcp-remote opens a browser window to complete sign-in with your Demiton account. No API key is stored in the config.

Then ask Claude: “What civil contractors were awarded Cross River Rail packages?” or “What were the weather conditions at Morningside in March 2024?”

When you’re ready to query your own contract data, upgrade to Insights.
