[BUG] Un-controllable Token Exceed with MCP results

[sihangchen97]

Problem (one or two sentences)

The conversation will get stuck when MCP tools return a large amount of context.

• with “Compression API failed: OpenAI completion error: 400 request (359746 tokens) exceeds the available context size (128000 tokens), try increasing it”

Context (who is affected and when)

N/A

Reproduction steps

1. Clone a rather large git repo
2. Activate "Git Tools" from "Zoo Marketplace - MCP"
3. Ask Zoo to check the diff and status of this git repo
4. Zoo will use the MCP tool for the task
5. The conversation gets stuck with a compression error

Expected result

Run normally with either trunc or compressed MCP result

Actual result

“Compression API failed: OpenAI completion error: 400 request (359746 tokens) exceeds the available context size (128000 tokens), try increasing it”

I can confirm. This happens with html_get use with a browser mcp (playwright) as well. A large html dump will take the context over 1M sometimes and then the session is borked.
