Firecrawl MCP Server times out with URLs containing @ symbol

Description

The firecrawl-mcp-server times out when processing URLs containing the @ symbol in the path (specifically npm scoped packages), while identical operations succeed with URLs without this character.

Steps to Reproduce

1. Send a URL with @ symbol to Firecrawl MCP via n8n: https://www.npmjs.com/package/@fancyheat/n8n-nodes-redis-enhanced Result: MCP error -32001 Request timed out (60000ms)

2. Send the same content via GitHub URL without @: https://github.com/fancyHeat/n8n-nodes-redis-enhanced Result: ✅ Success (execution completes normally)

Expected Behavior

Both URLs should be processed without timing out. The @ symbol is a valid URL character (used in npm scoped packages: @scope/package-name) and should be handled transparently.

Actual Behavior

URLs containing @ symbols trigger a 60-second MCP protocol timeout, causing the request to fail.

Reproducible Example

Execution 2599 (fails):

• Input: npm URL with @fancyheat
• Error: McpError: MCP error -32001: Request timed out
• Duration: 60000ms timeout

Execution 2579 (succeeds):

• Input: GitHub URL without @
• Result: Success
• Duration: ~5000ms

Environment

• firecrawl-mcp-server: v3.6.2 (latest)
• n8n: latest
• Transport: HTTP_STREAMABLE_SERVER mode

Possible Root Cause

The @ symbol may not be properly URL-encoded when Firecrawl MCP prepares the request to scrape, causing the Firecrawl API or the MCP protocol layer to hang or error out silently before timing out.
