What is the Unphurl MCP MCP server?

If you already use Unphurl MCP, the unphurl mcp mcp server is the piece that lets your assistant work with it directly. URL intelligence for AI agents and developers. Structured signals on all URLs. 16 tools, 25 signal weights. 20 free checks.

What the server does

Give your AI agent eyes for URLs. Unphurl analyses any URL across 7 dimensions (redirect behaviour, brand impersonation, domain age, SSL/TLS, parked detection, URL structure, DNS enrichment) and returns structured signals with a configurable 0-100 risk score. Signals, not verdicts. Your agent decides what to do with them.

Installation

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • Spreadsheets — Read a CRM export, batch-check every URL, write results back with risk scores
  • Documents — Generate a branded PDF audit report from the results
  • signup — Create a new account, get an API key
  • resend_verification — Resend verification email (3/hour limit)
  • check_url — Check a single URL across all 7 dimensions
  • check_urls — Batch check up to 500 URLs (handles async polling automatically)
  • list_profiles — List your custom scoring profiles
  • create_profile — Create or update a scoring profile with custom weights
  • delete_profile — Delete a scoring profile
  • show_defaults — Show all 25 scoring signals with default weights
  • get_balance — Check your pipeline check credit balance
  • get_stats — View usage statistics and score threshold counts

Credentials and setup notes

Configuration is passed through the environment: UNPHURL_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Worth knowing first

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Unphurl MCP.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

This sits in the payments and commerce group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Unphurl MCP's toolset — Spreadsheets, Documents, signup and 11 more — is a fair guide to whether it matches your workflow. It is maintained by 123ergo; worth a glance at recent repository activity before you build anything load-bearing on it.
