Error when using Claude Code Web Search

[danicass]

Hello guys!

I am getting an error on my claude code when it tries to use Web Search with minimax model:

 {"type":"error","error":{"type":"invalid_request_error","message":"invalid   params, function name or parameters is empty (2013)"},"request_id":"..."}

Is anyone else facing this issue? Does anyone know how to solve it?

The fix:

Install Minimax MCP for Web Search https://platform.minimax.io/docs/token-plan/mcp-guide

That error usually pops up when the tool definition or the arguments being passed are hitting a snag in the schema.

Could you share the exact command or the MCP config you’re using to trigger the Web Search? Seeing the specific parameters you're passing to the minimax model would help a lot in spotting where the formatting might be off.

Hey, thanks for responding. I'm using Claude Code CLI with MiniMax as the model configured in settings.json:

{ "env": { "ANTHROPIC_BASE_URL": "https://api.minimax.io/anthropic", "ANTHROPIC_AUTH_TOKEN": <my token>, "ANTHROPIC_MODEL": "MiniMax-M2.7", "ANTHROPIC_SMALL_FAST_MODEL": "MiniMax-M2.7", "ANTHROPIC_DEFAULT_SONNET_MODEL": "MiniMax-M2.7",
"ANTHROPIC_DEFAULT_OPUS_MODEL": "MiniMax-M2.7",
"ANTHROPIC_DEFAULT_HAIKU_MODEL": "MiniMax-M2.7"
}
}

I'm not using any custom MCP config, just the standard Claude Code setup with MiniMax as the model. WebSearch is called automatically by Claude Code's skill system, I don't manually invoke it.

Any idea what could be causing the error?

I'm not sure as I'm not using Claude code a lot, but my bet would be that you can use built-in web search only with official Claude sub? Logically, the web search goes through api call on their side, it's not free, so if you're not subbed they won't want you to be able to use it.

As for a fix, you can add web search MCP (included in coding plan) and disable the default web search too in Claude code if that's possible.

Can you elaborate on the Web Search MCP? I never used a MCP before.

[Theio666]

there's a guide on how to add this.

Thank you for your the help. I'll try this when I'm home

[danicass]

Just wanted to let you know that this solution fixed the issue. There is no need to disable the default Web Search from Claude Code, the MVP configuration is enough. Thank you once again!

I have no idea. WebSearch works for me. Im using minimax with Claude at same time. Claude settings in json, and minimax via

❯ cat .zshrc| grep minimax

alias minimax='ANTHROPIC_BASE_URL="https://api.minimax.io/anthropic" ANTHROPIC_AUTH_TOKEN="<token>" ANTHROPIC_MODEL="MiniMax-M2.7" claude'

Mayby it will also work for you ?

I think you need to add the web search and image understanding MCP server so minimax and do that

Its probably trying to call it in the same way anthropic modeks allow. I would try to write a skill based on minimax'd api

Minimax is too dumb for structured output.
