That's too much friction.
BlockRun MCP gives you access to 30+ AI models with:
claude mcp add blockrun npx @blockrun/mcp
Alternative: Prefer Python? Try the BlockRun Skill (
pip install blockrun-llm) - same features, different integration style.
claude mcp add blockrun npx @blockrun/mcp
A wallet is automatically created for you.
You: blockrun setup
Claude: Your wallet address is 0x...
Send USDC on Base network to fund it.
Send USDC to your wallet address on Base network. Even $5 gets you hundreds of requests.
| Method | Steps |
|---|---|
| From Coinbase | Send → USDC → Select "Base" network → Paste your address |
| Bridge | bridge.base.org → Bridge USDC to Base |
| Buy Direct | Coinbase Onramp → Buy USDC on Base |
Just ask naturally:
You: blockrun ask GPT-5 to explain quantum computing
You: blockrun chat with Claude Opus about this error
You: blockrun generate an image of a mountain sunset
blockrun ask GPT-5 what causes aurora borealis
blockrun chat with Claude Opus about optimizing this algorithm
blockrun ask Gemini Pro to review this code for security issues

Your wallet needs funding. Say blockrun setup to get your address and funding instructions.
The MCP couldn't find or create a wallet. Check that ~/.blockrun/ directory is writable.
Some models have rate limits. Try blockrun smart cheap or blockrun smart fast to use alternative models.
Say blockrun balance to check your on-chain USDC balance, or visit: https://basescan.org/address/YOUR_ADDRESS
If you've set a session budget and hit the limit, use blockrun budget clear to remove it or blockrun budget set $X to increase it.
