return_char_limit feature for mcp tools

[Jonathan-Harker]

Hi many thanks for such a great product. LETTA really makes a huge difference when building LLM solutions.

When defining my own functions I can pass the return_char_limit var to the upsert_from_function function as so

client.tools.upsert_from_function(func=function, return_char_limit=20_000)

Is it possible to add the same override to add_mcp_tool function. At the moment my results are truncated by the global constant. With large context windows now available this seems very limiting.

client.tools.add_mcp_tool(mcp_server_name=server, mcp_tool_name=tool.name) # No return_char_limit override available

Unless there are other ways to override the constants such as through ENV VARS that I don't know about?

Many thanks for your hard work on this amazing platform,

Jonathan
