HammerTech MCP by usefulapi

HammerTech MCP by usefulapi

Use your HammerTech account from Claude, Cursor, or any MCP client. Read projects, inspections, issues, incidents, permits and site sign-ins, read-only. Hosted, no local install: connect with your own credentials.

Live endpoint: https://hammertech.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://hammertech.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http hammertech https://hammertech.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "hammertech": {
      "url": "https://hammertech.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your HammerTech credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/hammertech/

On first connect you provide your HammerTech tenant (the part before .hammertechonline.com), a Region (au, us or eu), and a HammerTech API key (My Account → API Keys, created by a company admin). The server validates it and stores it per user. No keys go in config files.

Pricing

Plan	Price	Limit
Free	$0	50 tool calls / month
Pro (per user)	$9/mo or $90/yr (2 months free)	10,000 tool calls / month
Pro+ (per user)	$39/mo or $390/yr (2 months free)	100,000 tool calls / month

Each paid plan covers this server only. Ask your AI to run hammertech_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with hammertech_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with hammertech_upgrade before then undoes the cancel. Or write to [email protected].
