5 Free Claude MCPs That Feel Illegal to Know

Out of the box, Claude cannot open a website, research anything from today, make an image, or read the current docs for the thing you are building. These 5 fix all of it, and one prompt installs every one. No code.

Zach Sep 2026 · 7 prompts

What's In This Guide

  • The one prompt that installs all 5 MCPs at once, no code and no config files
  • What each one actually turns Claude into, in plain English
  • Which ones are truly free, which need a key, and exactly where to get it
  • A copy-paste test for each so you feel it working in the first 10 seconds
  • The 4 combos where two MCPs together do something neither can do alone
  • One stack test that runs all 5 on a single job

What An MCP Actually Is

An MCP is a plug. It connects Claude to a tool that lives outside of Claude, so Claude can go use that tool on its own instead of telling you how to use it.

Without one, Claude is a very smart person locked in a room with no phone and no internet. Every MCP you add is another thing you hand through the door. A browser. A research engine. A camera. The docs.

You install them once. They stay. Every future chat has them.

One Prompt, All 5 Installed

You do not install these one at a time. You hand the whole list to Claude Code and it installs itself while you watch. Open Claude Code and paste this in:

Paste into Claude Code 
Install these 5 MCP servers into my Claude Code at user (global) scope so they work in every project. Run the commands for me one at a time and tell me what happened after each one.

Three of them need nothing at all. Two of them (Perplexity, Firecrawl) need a free API key. Before you run those two, STOP and ask me to paste the key, or let me tell you to skip it for now and add it later.

1. Playwright (nothing needed):
claude mcp add -s user playwright -- npx -y @playwright/mcp@latest

2. Context7 (nothing needed):
claude mcp add -s user --transport http context7 https://mcp.context7.com/mcp

3. Higgsfield (no key, browser login on first use):
claude mcp add -s user --transport http higgsfield https://mcp.higgsfield.ai/mcp

4. Perplexity (needs a key, ask me first):
claude mcp add -s user perplexity --env PERPLEXITY_API_KEY="MY_KEY" -- npx -y @perplexity-ai/mcp-server

5. Firecrawl (needs a key, ask me first):
claude mcp add -s user firecrawl --env FIRECRAWL_API_KEY="MY_KEY" -- npx -y firecrawl-mcp

When you are done, run "claude mcp list" and show me the output so I can confirm which ones are connected. If any of them failed, tell me exactly which one and what the error said.

Playwright, Context7, and Higgsfield go in instantly. For Perplexity and Firecrawl, Claude stops and asks for the key. Do not have them yet? Say "skip Perplexity and Firecrawl for now" and add them later by pasting the same command with your key in it. Nothing breaks.

What Each One Actually Does

Five tools, five different jobs. Here is what becomes possible once each one is in, plus the single command if you would rather add them one at a time, and a prompt to try the second it connects.

1. Perplexity

Free key

Claude stops guessing and starts reading today.

Claude is trained on the past. Ask it about anything that happened recently and it either hedges or confidently makes something up. This plugs it into Perplexity, which is built for one thing: pulling live, cited information off the internet right now.

The part that feels illegal is that you stop doing research. You give Claude the question and it comes back with the answer plus the sources, in the same chat where you are already working.

Install just this one 
claude mcp add -s user perplexity --env PERPLEXITY_API_KEY="MY_KEY" -- npx -y @perplexity-ai/mcp-server
Try it 
"Research what changed in my industry in the last 30 days and bring me sources for every claim."

2. Higgsfield

Free to connect

Every top image and video model, in one connection.

This connects Claude to the best AI image and video models in one place. Nano Banana, Soul, Flux, Seedream, Kling, Veo, and Higgsfield’s own models. One connection instead of thirty browser tabs and thirty logins.

Once it is in, Claude can generate and edit images and video from the chat you are already in, build ads and UGC-style clips from a single prompt, then upscale, reframe, and clean up whatever it made. Your text tool just became a creative team.

Install just this one 
claude mcp add -s user --transport http higgsfield https://mcp.higgsfield.ai/mcp
Try it 
"Generate 3 scroll-stopping thumbnail options for a video about AI agents, then upscale the best one."

3. Playwright

Nothing needed

Claude gets a real browser it can actually drive.

This hands Claude a browser. It can open a site, click through it, fill out forms, log in, scroll, and pull whatever is on the screen. Not a description of a browser. A real one, running on your machine.

Here is why it matters more than it sounds: it lets Claude use any tool that has no API and no MCP. That is most tools. If you can do it in a browser, Claude can now do it for you.

Install just this one 
claude mcp add -s user playwright -- npx -y @playwright/mcp@latest
Try it 
"Open my analytics dashboard, log in, and pull last week’s numbers into a table."

4. Context7

Nothing needed

Claude reads the current docs instead of remembering old ones.

This is the one nobody talks about and it fixes the single most annoying thing about building with AI. Claude writes code using whatever version of a tool it learned about months ago. The tool has changed since. The code breaks. You spend an hour on an error that was never your fault.

Context7 pulls the current, real documentation for whatever library or tool you are using and feeds it to Claude before it writes anything. Add the words "use context7" to your prompt and the guessing stops. Free, no key, no account.

Install just this one 
claude mcp add -s user --transport http context7 https://mcp.context7.com/mcp
Try it 
"Set up authentication in my app using the current docs. Use context7."

5. Firecrawl

Free key

The entire web, turned into something Claude can read.

Firecrawl lets Claude search, scrape, crawl, and map any website. One page or a thousand. It turns a messy site into clean text Claude can actually work with, and it can pull structured data out on command: prices, emails, brand colors, offers, whatever you name.

If you do anything with marketing, this is the one. It is the difference between "I cannot access that page" and "here is everything on their site, organized the way you asked."

Install just this one 
claude mcp add -s user firecrawl --env FIRECRAWL_API_KEY="MY_KEY" -- npx -y firecrawl-mcp
Try it 
"Crawl this competitor’s site and pull every offer, price, and headline into a table."

Getting The Two Keys

Playwright and Context7 need nothing at all. Higgsfield logs you in through a browser the first time Claude uses it. Only two of the five need a key, and both take about a minute.

Perplexity

  1. Go to perplexity.ai and sign in.
  2. Open Settings, then API (perplexity.ai/settings/api).
  3. Generate a key and copy it.
  4. Paste it when Claude Code asks.

The key is free to create. The API itself runs on a small prepaid balance, so you may need a few dollars of credit. A little goes a long way.

Firecrawl

  1. Go to firecrawl.dev and sign up free.
  2. Open your dashboard and find API Keys.
  3. Copy your key.
  4. Paste it when Claude Code asks.

The free tier covers plenty for normal use. You will know when you outgrow it.

Higgsfield (no key, just a login)

  1. Sign up free at higgsfield.ai.
  2. Run the install command.
  3. The first time Claude calls a Higgsfield tool, a browser tab opens to log in.
  4. Approve it. You are connected.

Connecting costs nothing. Generating is pay per use, and most images are a few cents. Video costs more, so start with images.

The 4 Combos Nobody Uses

Most people install an MCP and use it alone. The whole point is that Claude can reach for two or three in the same job without you telling it how. These four are the ones I actually use.

  • 1. Firecrawl + Higgsfield

    Scrape a brand, then create in their look

    Firecrawl pulls a company’s real colors, fonts, and product shots off their site. Higgsfield generates new creative that matches. Ask Claude to scrape the brand, then make three ad concepts in that exact style. This is a whole agency workflow in one prompt.

  • 2. Perplexity + Context7

    Research the tool, then build with it correctly

    Perplexity finds which tool is actually best for what you are trying to build right now. Context7 pulls that tool’s current docs so Claude writes working code instead of code that used to work in March. Together they kill the two biggest ways AI builds break.

  • 3. Playwright + Firecrawl

    Get behind the login wall

    Firecrawl is faster on public pages. Playwright can log in. Chain them and Claude handles both: scrape everything public at speed, then drive a real browser for the parts that need an account. Nothing on the internet is off limits after that.

  • 4. Perplexity + Firecrawl

    Find the sources, then read them in full

    Perplexity tells you which 10 pages matter and cites them. Firecrawl goes and reads all 10 completely instead of the snippet. You get real depth rather than a summary of a summary, and Claude has the actual text to work from.

The One Job That Uses All 5

Reading about this does nothing. Run this once and you will get it. Swap in a real competitor and paste it into Claude Code after the install.

The stack test 
Use all 5 of my new MCPs on one job so I can see them work together.

The job: I want a one-page competitor breakdown for [PUT A COMPETITOR'S WEBSITE HERE].

1. Use Firecrawl to scrape their site. Pull their offers, pricing, headlines, brand colors, and fonts.
2. Use Perplexity to research what people are actually saying about them right now: recent news, reviews, complaints, and how they position themselves.
3. Use Playwright to open their site in a real browser and check what only shows up live: popups, chat widgets, cookie banners, anything gated behind a click.
4. Use Higgsfield to generate one image that shows how I would position against them.
5. Write the whole thing up as a single markdown file called competitor-breakdown.md with sections for Offers, Positioning, What People Say, Gaps I Can Attack, and Next Move.

Do not summarize what you are about to do. Just do it, then show me the file.

That single prompt is four tools you would have used separately, plus an hour of tab switching, done in one pass while you watch. That is the part that feels illegal.

Confirm All 5 Are Live

After the install and a restart, run this in Claude Code:

Terminal 
claude mcp list

You should see all five listed and connected: perplexity, higgsfield, playwright, context7, firecrawl. If one shows an error, here is the fix:

  • Auth error on Perplexity or Firecrawl
    The key did not save. Re-run that one command with your real key in place of MY_KEY.
  • Higgsfield says "not authenticated"
    The browser login never finished. Ask Claude to call any Higgsfield tool again, then approve the tab that opens. Make sure you are signed into the right account first.
  • Context7 connects but Claude ignores it
    Put the words use context7 in the prompt. It is the trigger. Without it Claude falls back on what it already thinks it knows.
  • A tool only works in one folder
    You missed the -s user flag. Re-run that command with it added.
  • Nothing shows up at all
    You did not restart. Close Claude Code fully and reopen it. Still stuck? Ask Claude directly: "my firecrawl MCP shows an error, help me fix it." It usually sorts itself out.

It Was Never The Model

Most people run Claude with none of this and decide AI is overhyped. It is not the model. It is that the model has no hands. These five give it live research (Perplexity), a creative studio (Higgsfield), a real browser (Playwright), the current docs (Context7), and the whole web (Firecrawl).

One paste to install. Two free keys and one login. Ten minutes, done once, and every chat you have from now on is a different tool.
