Frequently Asked Questions

Mcpproxy Go vs Spider Cloud: which should you choose?

Pick MCPProxy Go if you're an AI agent developer juggling multiple MCP servers and need to bypass tool limits with built-in security gates. Choose Spider Cloud when your priority is feeding fresh web data into RAG pipelines or LLM agents — its Rust-based scraping + Browser AI commands deliver fast, reliable crawling at pennies per thousand pages. The two tools solve completely different problems: MCPProxy is a control plane for MCP tools, Spider Cloud is a data plane for web content.

Can I use both tools together?

Yes. MCPProxy feeds tool calls to AI agents; Spider Cloud fetches web data. An agent using MCPProxy could call a Spider Cloud tool through an MCP server wrapper.

Does MCPProxy require cloud hosting?

No, MCPProxy runs entirely as a desktop app on your local machine — offline, no cloud needed.

Does Spider Cloud have a free tier?

Yes, Spider Cloud offers a free tier with limited pages (exact quota not specified), then pay-as-you-go after that.

How does MCPProxy bypass OpenAI's 128-function limit?

It uses a single 'retrieve_tools' endpoint that uses BM25 search to return only the most relevant tools per request, drastically reducing the payload size.

What are Browser AI commands in Spider Cloud?

New in March 2026: Act (click, type, navigate), Extract (pull structured data), and Observe (describe screen) via WebSocket — powered by an AI model.
