MCP Servers

Token-efficient browser automation for LLM agents: semantic page snapshots and stable element IDs instead of raw DOM or screenshots, driving Chrome over CDP.

Website & web-app testing built for AI agents rather than raw browser bindings: 66 Playwright tools with hard assertions, auto form-fill, persistent authenticated sessions (incl. interactive login for 2FA/SSO), network mocking, real INP, and accessibility/SEO/GEO (llms.txt, AI-crawler access, WebMCP) + Lighthouse audits.

Design-debugging context for AI agents from a real Chrome: which CSS rule WINS with file:line, blast radius (how many other elements that rule styles) + a scoped-fix selector, WordPress/Elementor origin attribution, interaction timelines, live CSS fix trials, and pixel/alignment/WCAG-contrast audits. No AI inside — deterministic CDP.

🎖️ - Official Firecrawl server with live browser interaction (firecrawlinteract) — navigate, click, type, and scroll on a page before extraction, for JS-heavy or auth-gated sites. Also scrape, crawl, map, search, and extract.

In-browser debug bridge that injects into your running web app, so an agent can read the DOM, console logs and network requests, and click/fill/inspect the page. Runs inside the page (not an external CDP driver), so it works in any browser and inside Cypress/Playwright runs.

MCP server + Chrome extension that connects Claude Code to Chromium-based browsers (Arc, Vivaldi, Brave) where the official Claude in Chrome extension doesn't work — navigate, click, read pages, run JS, and record GIFs in the user's real browser.

Local-first MCP server (@peekdev/mcp) + Chrome extension that records your real authenticated browser session (rrweb DOM + console + network, PII-masked, to local SQLite) and lets AI coding agents query it or drive the browser. No cloud, no telemetry.

Rent real residential Chrome browsers from real humans — per-minute billing ($0.01/min), real fingerprints, residential IPs, no datacenter signals. MCP-native, with SDKs for Python, JS, LangChain, CrewAI, n8n. Crypto payouts.

Intent-aware visual verification for coding agents: the agent declares what a UI change should affect, and SnapDiff diffs the page against a baseline and flags anything that changed outside that intent for review or rollback — local screenshot capture via Playwright.

Pipe one-click browser-tab screenshots into any MCP client, 100% local — a companion extension captures, the local server stacks them and serves them to your LLM on demand.

Access and organize your open browser tabs, bookmarks, and recently opened links across every macOS browser from your AI client. Powered by the free SupaSidebar app.

AI-native web scraper MCP server. Single binary, returns clean markdown, MIT-licensed Firecrawl alternative.

Drive a local Playwright browser through residential proxies with the agent choosing the exit country/city and holding one sticky identity per task. 10 tools: launch, navigate, accessibility snapshot, click, type, content extraction, exit-IP verification, and per-task identity rotation. Free trial, no card.

The MCP server behind Constat: FDA & NHTSA regulatory-risk intelligence for agents — device compliance risk by 3-letter product code, parsed 510(k) premarket evidence with verbatim source quotes, predicate chains, postmarket drift signals, clearance-to-payment reimbursement pathways (NTAP/CPT/CMS), and NHTSA vehicle safety. 14 tools. Decision support, not regulatory advice. Hosted at constat.dev/api/mcp.

Condition-aware ingredient, product & supplement safety for agents, with provenance on every answer — a verdict, an evidence tier (Gold/Silver/Bronze), and a verifiable citation — across breastfeeding, pregnancy, histamine/MCAS, rosacea, HS, allergy and fertility lenses. 9 tools incl. validateclaim (fact-check a claim against curated cited sources) and checkrecall (FDA/consumer recall lookup by brand with Class I flagging and source URLs). Hosted at mcp.healthai.com.

Auditable UniProt MCP server: 41 tools over the UniProt knowledgebase (entries, features, variants, PTMs, GO terms, cross-references) with per-query SHA-256 provenance and offline replay. uvx uniprot-mcp-server

AlphaFold MCP server integrating AlphaFold DB with eight additional public biomedical data sources, backed by a local SQLite knowledge graph for structural-confidence, variant, disease/phenotype, drug-target, and orthology workflows. uvx alphafold-sovereign-mcp
