MCP: repeatedly hitting recursionLimit

[basilesportif]

Often, while running MCP tools that do a lot independently, I'll get the error:

error: [handleAbortError] AI response error; aborting request: Recursion limit of 25 reached without hitting a stop condition. You can increase the limit by setting the "recursionLimit" config key.

Troubleshooting URL: https://js.langchain.com/docs/troubleshooting/errors/GRAPH_RECURSION_LIMIT

Where is the config option to increase this?

This isn’t configurable yet but I’ll add an option soon.

Sounds good--I can see why it wasn't needed before, but it becomes important when various MCP tools get deep in solving a task, only to break midway through.

I'm also hitting this a lot, especially when using an agent to write and then test code.
