Overview

AI-generated overview

Searches and verifies licensed fire protection contractors in Texas and California from state license records.

What you can do
  • Search fire protection companies by state, city, county, service type (fire sprinkler, fire alarm, fire extinguisher) or company name
  • Look up a company by directory slug or by any of its state license or registration numbers
  • Check whether a license or registration is active, who holds it, and when it expires
When to use it
Useful when you need to find or vet fire protection contractors in Texas or California, for example to shortlist vendors or confirm that a license number is active before hiring.
Requirements
A remote MCP endpoint; no packages, environment variables or headers are declared. Network access to the provider's endpoint is required.
Before you install
Data is a periodic snapshot of state records, so the official state lookup should be treated as authoritative for time-sensitive decisions. No authentication is declared, so queries are presumably not tied to an account.

Installation

In SourceWeft

  1. Open Plumb Registry in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.plumbregistry%2Fdirectory/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Search licensed fire protection companies

Find fire protection companies with an active state license. Covered: Texas (Texas State Fire Marshal's Office) and California (California Contractors State License Board). Filter by state, city, county, service (fire-sprinkler, fire-alarm, fire-extinguisher) or company name. With a city, results list companies with an office in that city first, then others in the same county; within each group the order is alphabetical (no company pays for placement). Every result includes license numbers, expiration dates, the regulator, a page URL and a cite_as string; please cite the URL when you use a result.
