LeadShield Contact Form & B2B Solicitation Blocker MCP

Website: ghlagencymcp.com/use-cases/ghl-contact-form-spam-blocker

LeadShield is a 2-stage contact form spam and B2B cold-pitch solicitation blocker for GoHighLevel (GHL), WordPress, HubSpot, and custom websites. It stops SEO pitches, web-design solicitors, offshore lead-gen agencies, and automated form bots before they trigger client SMS/email alerts or pollute CRM pipelines — while silently returning "Message sent" to spammers so bots never adapt or retry.

Quick start

  1. Visit LeadShield Contact Form & B2B Solicitation Blocker for architecture diagrams, CRM setup guides, and policy presets.
  2. Connect any MCP client to https://rankandrent-leads.hallmanlab.workers.dev/mcp (streamable-http), or install directly in your preferred host:
    • VS Code (1-Click MCP): Install LeadShield MCP in VS Code
    • Claude Code: /plugin marketplace add mooshee/leadshield-mcp then /plugin install leadshield@leadshield
    • Gemini CLI: gemini extensions install https://github.com/mooshee/leadshield-mcp
    • Devin CLI: devin plugins install mooshee/leadshield-mcp
    • Vercel Skills (skills.sh): npx skills add mooshee/leadshield-mcp
    • ClawHub: clawhub install leadshield-form-spam-blocker

Core Capabilities (5 Live MCP Tools)

1. 2-Stage Contact Form Screening (leadshield_screen_submission)
  • Stage 0 Deterministic Edge Drop ($0.00 / 0 billable units): Blocks honeypot fills, sub-1.2s automated fills, disposable emails, link shorteners, promotional URLs, foreign phone prefixes, and known B2B solicitation templates in under 1 ms.
  • Stage 1 Buyer-Intent Classification ($0.01/submission on Pay-As-You-Go): Evaluates human-written messages that pass Stage 0 to separate genuine local customers asking for a quote or appointment from vendors pitching services.
  • Returns allowed, blocked, verdict (verified_lead or blocked_spam), branch (deliver_to_client or spam_quarantine), stage, category, reason, and customerProbability.
2. Blocked Spam Reports & Weekly Audit Summaries (leadshield_get_blocked_spam_report)
  • Query quarantined contact form spam counts, Stage 0 vs Stage 1 breakdowns, and top spam categories (link_solicitation, b2b_solicitation, geographic_mismatch, bot_honeypot) by client slug and date window.
3. Server-Side Policy Inspection & 10 Form-Type Presets (leadshield_get_spam_policy)
  • Inspect effective per-site rules and preview any of the 10 built-in formType presets (general_inquiry, quote_request, booking_request, b2b_partnership, support_ticket, careers_application, warranty_claim, event_registration, newsletter_signup, feedback_review).
4. Custom Country, Phone Format, URL & Keyword Policy Configuration (leadshield_configure_spam_policy)
  • Preview (dryRun: true) or update server-side policies (allowedCountries, allowedPhoneFormats, blockUrlsInMessage, maxUrls, blockedKeywords, requiredKeywords) stored in R2 so browser scripts never expose filter heuristics.
5. Zero-Trust Script Embed & CRM Webhook Generator (leadshield_generate_guard_embed)
  • Generate the 1-line <script src="https://rankandrent-leads.hallmanlab.workers.dev/guard.js" data-site="..." defer></script> tag, HighLevel Workflow Action config, WordPress plugin setup, or HubSpot Workflow Webhook config.
