Setup
Setup guide
- 1In Switchy, open your workspace settings and navigate to the Integrations tab. Click 'Add MCP Integration' and select Openperplex from the list. You'll be prompted to paste an API key—get yours from the Openperplex dashboard under API Settings. Once you paste the key and click Connect, Switchy tests the connection by calling a lightweight search endpoint. If the test succeeds, you'll see Openperplex listed as active. Head to any Space and type '@Openperplex' followed by a task like 'search for recent articles on AI regulation' to confirm the tools respond. The MCP exposes eight tools: custom search (with and without streaming), website markdown and text extraction, screenshot capture, URL-based document queries, and document search. No OAuth scopes to manage—just keep your API key secure.
What teammates see: by default, memories from Openperplex are scoped to the Space (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

@Openperplex search for recent developments in quantum computing error correction and stream the results as they come in
Streaming search results now. Found 12 relevant sources published in the last 30 days. Top results include: a Nature paper on surface code improvements (March 2024), IBM's blog post on their 1,000+ qubit processor error rates, and a preprint discussing topological qubit stability. Results include titles, URLs, publication dates, and brief excerpts. Stream completed in 4.2 seconds with citations ranked by relevance and recency.
This example shows the streaming search capability, which returns results progressively rather than all at once. Useful for time-sensitive research where you want to see findings immediately. Requires API key authentication and consumes search quota per query. Result quality depends on Openperplex's index coverage and ranking algorithm.
@Openperplex get the markdown content from https://example.com/technical-spec and extract the system requirements section
Retrieved markdown content from the specified URL (2,847 words total). The system requirements section indicates: minimum 16GB RAM, Python 3.9+, CUDA 11.8 for GPU acceleration, and Ubuntu 20.04 or macOS 12+. The markdown uses GitHub-flavored format with code blocks for installation commands and a table comparing CPU vs GPU performance benchmarks. Full document structure preserved including headers, lists, and inline code formatting.
Demonstrates web content extraction in structured markdown format, which preserves formatting better than plain text extraction. The AI can then parse and answer questions about the content. Requires the target URL to be publicly accessible—won't work behind authentication or paywalls. Markdown conversion quality varies by source page complexity.
@Openperplex query this documentation URL https://docs.example.com/api/v2 with the question 'What are the rate limits for the search endpoint?'
Queried the documentation and found: The search endpoint has a rate limit of 100 requests per minute for standard tier accounts and 500 requests per minute for enterprise tier. Rate limit headers are returned in responses: X-RateLimit-Remaining and X-RateLimit-Reset. Exceeding limits returns HTTP 429 with a retry-after value. The documentation also notes that batch search operations count as multiple requests based on query count.
This showcases the Query from URL tool, which combines document retrieval with natural language question-answering. The MCP fetches the content and applies the query, returning a targeted answer rather than the full document. Most effective with well-structured documentation. Response accuracy depends on how clearly the source material addresses the question.
Use-case deep-dives
When Openperplex beats manual research for feature discovery
A 6-person product team at a B2B SaaS company runs quarterly roadmap reviews where they scan competitor blogs, changelog pages, and feature announcements to spot trends. Openperplex's Custom Search with filtering lets them query "new AI features in project management tools" and pull structured results across 20+ competitor sites in under a minute, then use Get Website Markdown to archive the full context for later review. The real win is the Query from URL tool: drop a competitor's pricing page URL and ask "what enterprise features are gated behind the top tier" without opening a browser. If your team does this research monthly or more, and you're tracking 10+ competitors, Openperplex pays for itself in saved context-switching. If it's ad-hoc once a quarter, bookmark the sites and do it manually.
Why Openperplex works for distributed doc lookups
A 3-person support team at a dev tools startup fields questions that span their own docs, third-party integration guides, and community forum threads scattered across GitHub, Stack Overflow, and Discord archives. Openperplex's Search Documents and Custom Search Stream tools let them query "how to authenticate Stripe webhooks with Next.js" and get real-time results from multiple sources without toggling tabs or remembering which site hosts what. The Get Website Text tool extracts clean content from paywalled or JavaScript-heavy pages that normal scrapers choke on. This setup shines when your knowledge base is fragmented across 5+ external domains and your team answers 20+ tickets a day. If your docs are centralized in Notion or a single help center, you don't need this—just use native search.
When Openperplex replaces manual link aggregation
A solo content marketer at a fintech startup publishes a weekly newsletter summarizing regulatory updates, competitor moves, and industry commentary. Openperplex's Search Stream tool runs standing queries like "CFPB fintech guidance" and surfaces new results as they publish, while Get Website Screenshot captures visual proof of UI changes on competitor dashboards for side-by-side comparisons. The Custom Search with field selection lets her pull just headlines and publish dates to build a digest without opening 30 tabs. If you're publishing weekly or more and aggregating from 10+ sources, Openperplex cuts research time by half. If it's monthly or your sources have RSS feeds, stick with Feedly and save the API cost.
Frequently asked
What does the Openperplex MCP do in Switchy?
It lets your AI agents search the web, extract content from URLs, and query documents in real time. The eight tools cover custom search with filters, streaming results, pulling markdown or plain text from websites, capturing screenshots, and asking natural-language questions against web-hosted documents. Think of it as giving your workspace a programmable search engine and content scraper.
Do I need an Openperplex account to use this MCP?
Yes. You'll need an Openperplex API key, which means signing up on their platform and generating credentials. Paste the key into Switchy's connection flow and the MCP handles authentication from there. No OAuth dance—just a static key you copy once.
Can the Openperplex MCP search private or paywalled sites?
No. It fetches publicly accessible web content and documents. If a page sits behind a login or paywall, the tools won't see it. For internal knowledge bases or authenticated sources, connect a different MCP that supports those credentials or use Switchy's file-upload features instead.
How is this different from just using Google or browsing manually?
Your agents can trigger searches, parse results, and extract structured data without leaving the conversation. Instead of copying URLs and pasting snippets, the MCP pulls markdown, screenshots, or answers from documents on demand. It's faster for repetitive research tasks and keeps the workflow inside Switchy.
Who on the team should connect the Openperplex MCP?
Anyone who needs agents to pull live web data—researchers, content writers, analysts. Because it uses an API key rather than OAuth, one person can connect it and the whole workspace benefits. Just make sure whoever holds the key understands it counts against Openperplex's rate limits, not Switchy's.
