Setup
Setup guide
- 11. Sign up at Klazify and copy your API key from the dashboard. 2. In Switchy, open Settings → Integrations → Developer Tools and click Connect next to Klazify. 3. Paste your API key into the prompt and click Authorize. 4. Switchy confirms the connection and shows Klazify's eight tools in the integration card. 5. Open any Space, type '@Klazify categorize example.com' and send — the bot replies with IAB categories and confidence scores. 6. Test a second tool by asking '@Klazify get company data for stripe.com' to verify firmographic lookups work. 7. If a request fails, check your Klazify dashboard for quota limits or key validity. 8. Invite teammates who do prospect research or competitive analysis so they can @mention Klazify in shared Spaces.
What teammates see: by default, memories from Klazify are scoped to the Space (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

@Klazify can you categorize stripe.com and show me its IAB classifications with confidence scores?
Based on Klazify's analysis, stripe.com falls into these IAB V3 categories: Business and Finance > Business Software (confidence: 0.94), Technology & Computing > Software (confidence: 0.89), and Business and Finance > Payment Processing (confidence: 0.87). The high confidence scores indicate strong classification certainty. This example illustrates how Klazify maps domains to its 620+ category taxonomy, useful for content filtering, ad targeting, or market segmentation.
This showcases Klazify's core categorization engine. Requires an API key with categorization access. Confidence scores help you assess reliability—anything above 0.80 is typically considered strong. Note that categories reflect the domain's primary content at analysis time; sites with diverse content may span multiple categories.
@Klazify pull the full company profile for shopify.com including employee count, revenue estimates, and funding data.
Klazify returns: Shopify Inc. is headquartered in Ottawa, Canada with approximately 10,000+ employees. Estimated annual revenue: $5.6B (2023). The company has raised $122M in total funding across multiple rounds. Industry classifications include E-commerce Platform, SaaS, and Retail Technology. This example demonstrates how Klazify enriches domain data with business intelligence, combining public records and proprietary analysis to provide firmographic context.
This write demonstrates Klazify's business intelligence layer beyond categorization. Data accuracy depends on public availability—private companies or recent changes may show estimates rather than confirmed figures. Useful for lead enrichment, market research, or competitive analysis. Revenue and employee counts are periodically updated but not real-time.
@Klazify compare the tech stacks of vercel.com and netlify.com, then summarize which platform uses more modern infrastructure tooling.
Vercel's stack includes: Next.js (framework), Cloudflare (CDN), AWS (infrastructure), Turborepo (build system), and Edge Functions. Netlify uses: React (framework), Netlify Edge (CDN), AWS (infrastructure), and Netlify Functions. Analysis: Both platforms leverage edge computing and AWS backbone, but Vercel shows tighter integration with its own Next.js framework and Turborepo for monorepo optimization. Netlify maintains framework-agnostic tooling. This example shows how Klazify's tech stack detection enables competitive infrastructure analysis when paired with AI reasoning.
This synthesis example combines Klazify's tech stack tool with AI interpretation. The MCP detects technologies via website fingerprinting—accuracy is high for client-side tech but may miss proprietary backend systems. Ideal for competitive intelligence, sales prospecting (identifying companies using specific platforms), or migration planning. Stack data reflects what's publicly detectable, not necessarily the complete infrastructure.
Use-case deep-dives
When Klazify beats manual research for outbound lists
A 10-person B2B SaaS startup building outbound lists needs to qualify 200 inbound signups per week—filtering out students, freelancers, and non-target verticals before sales touches them. Klazify's Categorize URL and Get Company Data tools let the team run domains through IAB classification and pull employee count in one pass, then route qualified leads to the CRM. The confidence scores (returned with each category) help flag edge cases for manual review. This works until you hit enterprise scale: if you're processing 2,000+ domains daily, the per-call latency adds up and you'll want batch endpoints or a dedicated enrichment vendor. For early-stage teams running lean ops, Klazify turns a 4-hour weekly research slog into a 20-minute Switchy workflow.
How Get Tech Stack and Similar Companies speed positioning research
A 6-person product marketing team at a developer tools company needs to map the competitive landscape every quarter—who's using what stack, who's targeting the same buyer, and where the white space is. Klazify's Get Tech Stack tool pulls framework and platform data for any competitor domain, while Get Similar Companies surfaces adjacent players the team hasn't tracked yet. The combo gives you a snapshot of the category in 30 minutes instead of two days of manual scraping. The limit: tech stack data is surface-level (public-facing tools only, no internal infra), so this replaces breadth research, not deep technical teardowns. If your positioning hinges on infrastructure choices competitors don't advertise, you'll still need engineering interviews. For quarterly landscape updates and board deck ammo, Klazify gets the job done.
When domain metadata helps route inbound tickets faster
A 4-person support team at a no-code platform gets 50+ 'how do I integrate with [random SaaS tool]' tickets per week. Instead of Googling every domain to figure out what the tool does, they use Klazify's Categorize URL and Get Domain Logo tools in a Switchy prompt to auto-tag tickets with IAB category and visual context before assigning them. A ticket about 'integrate with acme-crm.io' gets tagged 'Business Software > CRM' and shows the logo, so the agent knows it's a CRM request before opening the thread. This shaves 90 seconds per ticket and prevents misroutes. The trade-off: if the inbound tool is brand-new or niche, Klazify's confidence score drops below 0.6 and you're back to manual lookup. For established SaaS ecosystems, it's a no-brainer time-saver.
Frequently asked
What does the Klazify MCP do in Switchy?
It lets your AI agents pull company data, tech stacks, social links, and IAB category tags for any domain — without leaving the chat. You ask about a competitor or prospect URL, and Klazify returns structured business intelligence: employee count, revenue estimates, logo, expiration dates, and which of 620+ categories the site falls into. Useful for research, lead enrichment, and competitive analysis inside your workspace.
Do I need a paid Klazify account to use this MCP?
Yes. You must have an active Klazify subscription and a valid API key. Switchy passes that key with every request, so the MCP inherits your plan's rate limits and feature access. Free-tier keys typically cap at a few hundred lookups per month; paid plans unlock higher quotas and additional data fields like funding rounds and precise revenue bands.
Can the Klazify MCP categorize websites in real time?
Yes. The Real Time Categorization tool runs AI-powered classification on demand, returning IAB V3 categories and confidence scores in seconds. It's faster than batch jobs but counts against your API quota. Use it when you need instant results for a URL someone just shared in chat; for bulk research, consider exporting a list and processing it outside Switchy to preserve credits.
How is this different from scraping company data myself?
Klazify aggregates dozens of public and proprietary sources — business registries, job boards, funding databases, DNS records — then normalizes the output into structured JSON. Scraping one site at a time is slower, breaks when layouts change, and misses cross-referenced signals like employee-growth trends. The MCP trades API cost for speed and reliability, especially when your team needs consistent data formats across hundreds of domains.
Who on the team should connect the Klazify MCP?
Whoever holds the Klazify API key and understands your lookup budget. Sales ops, growth, or BI roles are common owners because they already manage enrichment tools. Once connected, any Switchy member can invoke the tools in shared chats, but all requests draw from the same API quota — so set expectations about daily limits to avoid surprise overages mid-month.
