Windows: setup mcp fails with path quoting (C:\Program not recognized, v1.20.0)

[edwardjones3976]

Summary

firecrawl setup mcp (firecrawl-cli v1.20.0 on Windows) fails when spawning npx.cmd through cmd.exe because a spaced path is not quoted correctly:

'"C:\Program' is not recognized as an internal or external command,
operable program or batch file.
Error: Failed to configure Firecrawl MCP.

This reproduces for a single agent (-a cursor) and for --agent all. It is a CLI defect in runClientCommand / escapeCmdArg (see dist/commands/setup.js), not a user config issue.

Environment

• OS: Windows 11
• firecrawl-cli: 1.20.0 (latest per firecrawl doctor)
• Node: v24.19.0 under C:\Program Files\nodejs\ (path contains a space)
• Shell: PowerShell

Steps to reproduce

1. npm i -g firecrawl-cli@1.20.0
2. firecrawl setup mcp -g -a cursor -y --keyless
3. Observe the '"C:\Program' is not recognized error

Workaround (verified)

Bypass firecrawl's wrapper and call add-mcp directly from PowerShell/Node (which quotes Program Files correctly):

npx -y add-mcp@1.14.0 https://mcp.firecrawl.dev/v2/mcp --name firecrawl --transport http --global --all --yes

This successfully registered https://mcp.firecrawl.dev/v2/mcp on Cursor, Claude Code, Codex, Gemini CLI, VS Code/GitHub Copilot, Continue (manual YAML), and other detected agents.

Expected

firecrawl setup mcp should configure the hosted MCP URL on Windows even when Node/npm live under C:\Program Files\....

Notes

firecrawl doctor --query ... could not file this via /v2/support/ask here because no API key is present in this shell (Not authenticated). Opening this issue instead.
