DrillerDB MCP Server

Remote Model Context Protocol server for DrillerDB, the operating system for water-well and drilling contractors. Connect your DrillerDB account to Microsoft Copilot, Claude, ChatGPT, Codex, Cursor, VS Code, or any MCP client and work with your real jobs, customers, invoices, crews, and well logs in plain English.

https://mcp.drillerdb.com


Transport	Streamable HTTP
Authentication	OAuth 2.0 (Authorization Code + PKCE, Dynamic Client Registration)
Hosting	Managed by DrillerDB, LLC. Nothing to install or self-host.
Account	Requires an active DrillerDB account (app.drillerdb.com)
Registry name	`com.drillerdb/drillerdb`
Full docs	drillerdb.com/connectors/mcp

This repository holds the public documentation and the server.json registry manifest for the hosted DrillerDB MCP server. The server itself is a managed service and its source is not open.

Quick start

Add the server URL as a custom connector in your MCP client. OAuth sign-in happens automatically on first use, and access is scoped to your own DrillerDB company.

Claude Code

claude mcp add --transport http drillerdb https://mcp.drillerdb.com

Claude (web and desktop)

Settings -> Connectors -> Add custom connector, then paste https://mcp.drillerdb.com.

Microsoft Copilot

DrillerDB is preparing the server for Microsoft MCP certification. After Microsoft publishes the certified connector, administrators can enable it from Microsoft's agent and connector catalog. The same DrillerDB OAuth sign-in and company-level permissions apply.

Gemini CLI

Install the DrillerDB extension directly from this repository:

gemini extensions install https://github.com/CraigVG/drillerdb-mcp

Gemini CLI loads the managed endpoint from gemini-extension.json and starts the DrillerDB OAuth sign-in flow when you authenticate the server.

Cursor / VS Code / other clients

{
  "mcpServers": {
    "drillerdb": {
      "type": "http",
      "url": "https://mcp.drillerdb.com"
    }
  }
}

Your client discovers the OAuth endpoints automatically from /.well-known/oauth-protected-resource and the WWW-Authenticate header on a 401, so no client ID or secret needs to be configured by hand.

What you can ask

"Which jobs are ready to schedule this week?"
"What does Acme Farms still owe us, and how old is it?"
"Show me the well log for the Johnson project."
"How is revenue pacing this quarter compared to last?"
"Which rigs have maintenance coming due?"
"Draft the field report for today's crew and attach it to the job."

Permission scopes

Scope	Grants
`mcp:read`	Read projects, customers, invoices, proposals, work orders, crews, schedule, field reports, equipment, timecards, communications, inventory, and well logs
`mcp:write:low`	Trivially reversible writes, such as attaching a note or submitting a field report
`mcp:write:high`	State-changing writes, such as scheduling or dispatching a job or sending an invoice
`mcp:proposals:write`	Proposal generation and delivery

Higher-risk write tools are approval-gated: the tool returns an approval-required result first, and the action only runs once you approve it in the DrillerDB console. Nothing that contacts a customer or moves money happens without an explicit confirmation.

Security

Tenant isolation. Every query is filtered by the company_id bound to your OAuth token, never by tool input. There is no way to reach another contractor's data.
Audit log. Every tool call is recorded: who called it, which tool, when, and the outcome.
Revocable. You can revoke the connector's access at any time from your DrillerDB account, which immediately invalidates its tokens.
Rate limited. Per-consumer limits protect the service and your account.
First-party. DrillerDB owns the API and the data. No connector data is sold or used for advertising.

See the DrillerDB Privacy Policy for how data is collected, used, and retained.
