[Bug]: Enabling firecrawl mcp fails all google prompts - 400 Bad Request #48
Description
Description
Google models in opencode give the following error even when they don't need to use firecrawl.
So all google model prompts fail with the following error if firecrawl is enabled.
When I disable firecrawl google models work fine in opencode.
All other models work fine in opencode when firecrawl is enabled and they can use firecrawl normally.
I can also normally use firecrawl in gemini-cli and on vscode copilot with google models.
Reproduction Steps
Steps to reproduce the behavior:
I have authenticated with google oauth:
"google": {
"type": "oauth",
"refresh": "-----------------------",
"access": "--------------------------",
"expires": XXXXXXXX,
"email": "myemail"
}
I also have installed firecrawl mcp server in opencode.
"firecrawl": {
"enabled": true,
"type": "local",
"command": ["npx", "-y", "firecrawl-mcp"],
"environment": {
"FIRECRAWL_API_KEY": "XXXXXXXXXXXXXXXXXXXX",
},
},
Environment
- OS: Linux
Opencode Information
- Opencode Type: cli
- Opencode Version: 1.1.53

Additional Context
Again to be clear this happens only with google models when firecrawl mcp is enabled EVEN WHEN not used by the prompt, making all prompts fail with google models.
This is not critical, I can disable firecrawl to work with google models but it could be a more serious bug that affects other functionalities.
Also I see on the debug log errors about rateLimitExceeded but I don't have any problems using gemini models when firecrawl is disabled.
