🐍 Announcing Python Library for Code Mode
Code Mode now supports both Python and TypeScript! The same powerful code-execution approach to tool calling is now available across the two most popular AI development languages.
What's New
Python Library (code-mode on PyPI)
- Full feature parity with TypeScript library
- Native Python async/await syntax
- Process sandboxing with RestrictedPython
- Auto-generated TypedDict interfaces
- Same 60%+ token savings and performance gains
Why This Matters: Multi-Language AI Development
AI teams often split between Python (data science, ML frameworks) and TypeScript (web services, tooling). Now you can use Code Mode in both ecosystems:
Python Teams:
from utcp_code_mode import CodeModeUtcpClient
client = await CodeModeUtcpClient.create()
await client.register_manual({'name': 'github', ...})
result = await client.call_tool_chain("# Python code here")TypeScript Teams:
import { CodeModeUtcpClient } from '@utcp/code-mode';
const client = await CodeModeUtcpClient.create();
await client.registerManual({ name: 'github', ... });
const { result } = await client.callToolChain(`/* TypeScript */`);✨ Highlights in v2.0.0
Python Library (NEW)
- Package:
code-modeon PyPI (v0.0.3) - Secure execution: Process sandboxing with RestrictedPython
- Python-native interfaces: Auto-generated TypedDict definitions
- Enterprise features: Timeout protection, console capture, no network access
- Universal protocol support: MCP, HTTP, File, CLI sources
TypeScript Library (Stable)
- Package:
@utcp/code-modeon npm (v1.0.4) - VM sandboxing: Node.js isolated execution contexts
- TypeScript interfaces: Auto-generated type definitions
- Production-ready: Used in enterprise deployments
Both Libraries Share:
- Progressive tool discovery via
search_tools - Runtime introspection (
__interfaces,__get_tool_interface) - Multi-protocol support (MCP, HTTP, File, CLI)
- Complete observability (logs + results)
- Proven 60%+ token reduction vs traditional tool calling
🧪 Quickstart
Python
pip install code-modefrom utcp_code_mode import CodeModeUtcpClient
client = await CodeModeUtcpClient.create()
await client.register_manual({'name': 'github', 'call_template_type': 'mcp', ...})
result = await client.call_tool_chain('''
pr = await github.get_pull_request(owner='microsoft', repo='vscode', pull_number=1234)
return {"title": pr["title"], "state": pr["state"]}
''')TypeScript
npm install @utcp/code-modeimport { CodeModeUtcpClient } from '@utcp/code-mode';
const client = await CodeModeUtcpClient.create();
await client.registerManual({ name: 'github', call_template_type: 'mcp', ... });
const { result } = await client.callToolChain(`
const pr = await github.get_pull_request({ owner: 'microsoft', repo: 'vscode', pull_number: 1234 });
return { title: pr.title, state: pr.state };
`);🔐 Security & Enterprise Features
Both libraries provide:
- Isolated sandboxing – Process (Python) / VM (TypeScript) isolation
- Timeout protection – Configurable execution limits
- Zero external access – Tools only via registered servers
- Complete observability – Full console logs + error handling
- Restricted builtins – Dangerous functions blocked
