By name: browser description: Automate web page interactions via PinchTab for claiming airdrops and interacting with dApps
Browser Automation (PinchTab)
Use the browser tool for web page interaction via PinchTab.
When to Use
- User wants to claim an airdrop from a dApp UI
- User wants to interact with a DeFi protocol that has no API
- User needs to read content from a web dashboard
- User wants to fill out a form or connect a wallet on a website
- User needs to scrape on-chain dashboards or protocol docs
Prerequisites
PinchTab must be installed and running:
# Install (12MB Go binary)
curl -sSL https://pinchtab.com/install.sh | sh
# Start server
pinchtab serve
Default URL: http://localhost:9222. Override with PINCHTAB_URL env var.
Actions
| Action | Description | Required Params |
|---|---|---|
| navigate | Go to URL, extract page content | url |
| click | Click element by CSS selector | selector |
| type | Type text into input field | selector, text |
| extract | Extract structured data from page | (selector optional) |
| screenshot | Take page screenshot | (selector optional) |
| status | Check if PinchTab is running | (none) |
Common Flows
Check airdrop eligibility
browser action=navigate url=https://claim.example.com wait_for=".claim-button"
Then extract the eligibility status:
browser action=extract selector=".eligibility-status"
Claim an airdrop
browser action=navigate url=https://claim.example.com
browser action=click selector="button.connect-wallet"
browser action=click selector="button.claim"
Read protocol dashboard
browser action=navigate url=https://app.aave.com
browser action=extract selector=".markets-table" format=table
Fill and submit a form
browser action=navigate url=https://example.com/form
browser action=type selector="#email" text="user@example.com"
browser action=type selector="#amount" text="100"
browser action=click selector="button[type=submit]"
Check PinchTab status
browser action=status
Token Efficiency
PinchTab extracts structured text content (800 tokens/page) instead of sending screenshots (10K+ tokens). This makes it practical for LLM-driven web automation. Use extract for data retrieval and screenshot only when visual inspection is necessary.
Important Notes
- Stealth mode is on by default — bypasses common bot detection
- Requires PinchTab binary — tool reports clear error if not running
- CSS selectors — click/type/extract use standard CSS selectors (e.g.
"#id",".class","button.submit") - Content truncation — navigate limits content to ~4000 chars; use extract with a selector for specific content
- Not for bulk scraping — designed for interactive single-page operations. Use CF /crawl for batch research.
- No wallet connection — PinchTab browses the web but doesn't sign transactions. For dApp wallet interaction, the dApp needs WalletConnect or manual steps.
