Claude Connectors 5 free connectors that give Claude hands

Five connectors, one superpower each

A connector plugs Claude into a real tool, so it can do the job instead of describing it. All five are free to start. In Claude Code three work right away with no account, and PostHog and Composio ask you to sign in the first time, because they open your own data.

1. 1. ExaA search engine built for AI

   Claude searches the web and reads pages through Exa: you ask in plain words and get ready-to-use results with their links.

   Free No account and no key: free, with rate limits. Sign in to Exa later if you hit them.

2. 2. FirecrawlSees any website

   Claude reads any page as clean text or HTML, takes a screenshot, and pulls the site's brand kit: logo, colors and fonts.

   Free No account and no key: search, scrape and parse, within daily limits. A free account adds 1,000 credits every month, no card.

3. 3. PostHogA detective for your product

   Claude reads your PostHog data: the funnel step where people drop off, your top errors with the full stack trace, then the fix. It can also run feature flags and A/B tests.

   Free The connector is free. PostHog's free plan, no card, covers 1 million events, 5,000 session recordings and 100,000 tracked errors a month.

4. 4. PlaywrightGives Claude hands

   Claude drives a real browser: it opens pages, clicks, types, fills forms, picks from menus and uploads files. It works on any website, even an old tool with no API.

   Free Open source (Apache-2.0) from Microsoft. It runs on your computer and needs Node.js 18 or newer.

   Works right awayby Microsoft
5. 5. ComposioOne connector, 1,000+ apps

   One connector that opens 1,000+ apps to Claude, including Gmail, Slack, Notion, GitHub, Linear and HubSpot. The first time Claude needs an app, Composio gives you a sign-in link. After that the connection stays.

   Free Free Hobby plan, no credit card: 100,000 tool calls a month.

  • The order screen after SaveOrder 10482 was updated: Shipped (Tracking sent to the customer).

  An old-style order screen with no API, on my computer: it read the page, filled the order number, the status and a note, then clicked Save. Headless browser, Playwright MCP 0.0.83.

• PostHog and Composio

  Not tested by me

  They need your own account: PostHog reads the data it already collects on your site or app, and Composio asks you to approve each app. Their docs show funnels and errors with the full stack trace for PostHog, and Gmail, Slack, Notion, GitHub, Linear and HubSpot among Composio's 1,000+ apps.

  The one link, in a clean Claude Code

  Tested 23 Oct 2026
  $ claude mcp list
  exa: ✔ Connected
  firecrawl: ✔ Connected
  posthog: ! Needs authentication
  playwright: ✔ Connected
  composio: ! Needs authentication

  How I tested it. On 23 Oct 2026, in a clean copy of Claude Code 2.1.309 with an empty home folder, I pasted only the link. Claude read the file, showed the five commands and asked first. After my yes it ran them, and claude mcp list showed all five: exa, firecrawl and playwright Connected, posthog and composio Needs authentication (the sign-in comes on first use). A new session loaded all five. I ran that test twice on this same file: 2 of 2 passed. It ran with permissions pre-approved: in a normal session Claude also asks you before each command. I didn't sign in to PostHog or Composio in the test.

Honest limits

• Free has limits. Exa and Firecrawl without an account are rate limited, and Firecrawl caps each network per day. A free account with each raises the limits: the guide shows how.
• PostHog only reads what PostHog collects. No PostHog on your product, no data. A few of its AI-powered tools can count as PostHog AI usage, and only if you turned on AI data processing.
• Composio needs one approval per app, the first time Claude uses it.
• Playwright works in a browser. It opens a real browser window on your computer and can use any website, but it can't click inside desktop apps. It needs Node.js 18 or newer, and claude.ai on the web can't run it.
• One custom connector on claude.ai Free. Composio uses it.
• They act with your permissions. Connectors can read and change data in your accounts. Read what Claude is about to do before you allow it, and connect only tools you trust.
• What I didn't test. The sign-ins, PostHog and Composio on real data, the claude.ai and Desktop routes, Windows.
