MCP
Claude Desktop integration
In brief
The strongest case: remote MCP server at mcp.askmarcel.app with OAuth or API key. Claude calls diagnose and cites sources.
Prerequisites
- Claude account (Pro recommended for all tools)
- AskMarcel Developer API key (ak_live_) or OAuth flow
- Claude Desktop installed (macOS / Windows)
Recommended: OAuth
- 1
Open MCP settings
Claude Desktop → Settings → Developer → Edit Config (or Connectors depending on version).
- 2
Add remote connector
URL: https://mcp.askmarcel.app. Claude auto-detects OAuth via /.well-known/oauth-protected-resource.
- 3
Authorize AskMarcel
Follow the OAuth consent screen. Your AskMarcel account is linked — no key to paste.
Alternative: API key
If OAuth is unavailable, configure manually with your ak_live_ key.
claude_desktop_config.json
{
"mcpServers": {
"askmarcel": {
"url": "https://mcp.askmarcel.app",
"headers": {
"Authorization": "Bearer ak_live_..."
}
}
}
}Use the tools
Ask Claude: "Diagnose error E7 on a Mitsubishi Ecodan". The agent calls diagnose and shows steps + manufacturer source.
Verify it works
In Claude, ask "List available AskMarcel tools". You should see all 7 MCP tools.
Manual test (curl)
curl -s -X POST https://mcp.askmarcel.app \

-d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'Known limitations
- OAuth requires a linked AskMarcel account
- Developer tier is limited to 250 req/month and not allowed in production
