Tools & Capabilities Breakdown
Proxy4agents MCP Tools (9)
novada_proxy_fetch
Fetch any URL through a residential proxy. Returns structured JSON with content, status code, and metadata. Auto-retry on network errors. Caches repeated calls (default 300s TTL — `meta.cache_hit: true` means no proxy credit used).
novada_proxy_batch_fetch
Fetch 2–20 URLs concurrently through residential proxy. Up to 5x faster than sequential fetches. Per-URL errors are captured individually — the batch itself succeeds even if some URLs fail. Reuses response cache for URLs already fetched.
novada_proxy_extract
Extract structured fields from any URL using heuristic pattern matching (meta tags, Open Graph, JSON-LD, Schema.org). Lightweight — no LLM needed. Set `render_fallback: true` to automatically retry via real Chromium if the proxy fetch fails.
novada_proxy_map
Crawl a URL and return all internal links as a structured JSON array. Use as the discovery step before `novada_proxy_batch_fetch` to crawl an entire site without guessing URLs.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Proxy4agents MCP is categorized under Developer Tools and uses a local stdio subprocess. In contrast, Next Devtools MCP belongs to Developer Tools using local stdio subprocess. Select Proxy4agents MCP when you need capabilities focused on developer tools and Next Devtools MCP when you require tools for developer tools.
Sticky session fetch — every call with the same `session_id` uses the same residential IP. Essential for login flows, paginated scraping, and price monitoring. Supports `verify_sticky: true` to confirm IP consistency before relying on it.
novada_proxy_search
Structured Google search via Novada Scraper API. Returns titles, URLs, and snippets as clean JSON — no HTML parsing needed.
novada_proxy_crawl
Recursively crawl a website via BFS traversal. Starts from a URL, discovers links at each depth level, and returns the full URL tree with metadata.
novada_proxy_research
One-shot research tool — searches the web, fetches top results, and returns structured findings with source previews. The agent can analyze the findings for deeper synthesis.
novada_proxy_status
Check proxy network connectivity and version. Makes a live proxy call to verify the connection is working. No credentials required.
Next Devtools MCP Tools (4)
nextjs_index
Discover running Next.js dev servers and list each one's runtime MCP tools.
nextjs_call
Call a runtime tool on a discovered server (errors, routes, logs, Server Actions).
nextjs_docs
Gateway.** Point the agent at version-accurate docs in `node_modules/next/dist/docs/`.
browser_eval
Gateway.** Point the agent at the [`agent-browser`](https://github.com/vercel-labs/agent-browser) CLI for browser automation.
