Add Firecrawl’s search, scrape, crawl, and browser tools to OpenCode via MCP.

​
Quick Setup

​
1. Get Your API Key

Sign up at firecrawl.dev/app and copy your API key.

​
2. Add Firecrawl to OpenCode

OpenCode reads config from ~/.config/opencode/config.json (global) or ./opencode.json in your project. Add: 
{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "firecrawl": {
      "type": "local",
      "command": ["npx", "-y", "firecrawl-mcp"],
      "environment": {
        "FIRECRAWL_API_KEY": "fc-YOUR-API-KEY"
      }
    }
  }
}
Replace fc-YOUR-API-KEY with your Firecrawl API key.

​
3. Start OpenCode

opencode
OpenCode loads MCP servers on startup. Confirm Firecrawl is attached: 
/mcp

​
Quick Demo

Search the web for "Bun 2.0 changelog" and summarize the top results.

Scrape https://docs.firecrawl.dev/introduction and list the code examples.

Crawl https://example.com/blog and save each post as markdown.

​
Remote Hosted URL (no Node.js required)

{
  "mcp": {
    "firecrawl": {
      "type": "remote",
      "url": "https://mcp.firecrawl.dev/fc-YOUR-API-KEY/v2/mcp"
    }
  }
}

​
Troubleshooting

  • Server not attached — run opencode doctor to inspect MCP load errors.
  • Permission denied on npx — install Node.js 18+ and ensure your shell picks up the install (which npx).
