Module code_executor 

Code execution environment for agents using MCP tools programmatically.

This module allows agents to write and execute code snippets that interact with MCP tools as library functions, rather than making individual tool calls. This improves efficiency through:

• Control flow: loops, conditionals, error handling without repeated model calls
• Data filtering: process results before returning to model
• Latency: code runs locally with direct process execution
• Context: intermediate results stay local unless explicitly logged

Example

let executor = CodeExecutor::new(
    Language::Python3,
    Arc::new(mcp_client),
    PathBuf::from("/workspace"),
);

// Agent writes Python code
let code = r#"
files = list_files(path="/workspace", recursive=True)
filtered = [f for f in files if "test" in f]
result = {"count": len(filtered), "files": filtered[:10]}
"#;

let result = executor.execute(code).await?;
