MCP Web Search & Scrape in Qwen Code

​

Requirements

• Qwen Code 0.25 or newer.
• A Firecrawl API key, exported as FIRECRAWL_API_KEY.

​

Quick setup

1. Export your API key in the shell you start Qwen Code from:

export FIRECRAWL_API_KEY="fc-YOUR-API-KEY"

2. Add the server. Single quotes keep the shell from expanding the variable, so the settings file stores the reference instead of your key:

qwen mcp add --scope user --transport http firecrawl https://mcp.firecrawl.dev/v2/mcp \
  --header 'Authorization: Bearer $FIRECRAWL_API_KEY'

3. Confirm the server connects:

qwen mcp list

4. Start Qwen Code, run /mcp to see the Firecrawl tools, and ask it to search or scrape.

{
  "mcpServers": {
    "firecrawl": {
      "httpUrl": "https://mcp.firecrawl.dev/v2/mcp",
      "headers": {
        "Authorization": "Bearer $FIRECRAWL_API_KEY"
      }
    }
  }
}

Troubleshooting

• The server is missing in a running session: restart Qwen Code in the same project after adding it.
• The server shows as not connected: run qwen mcp list, and check that FIRECRAWL_API_KEY is exported in the shell that starts Qwen Code.
• Tool calls are rejected for an invalid key: confirm the header value is Bearer $FIRECRAWL_API_KEY and that the variable holds a valid key.
• Tools are not used: some models call MCP tools more reliably than others. Try a different model.
