I finally gathered and systematized all the tool options into a single comprehensive demo. Not yet a notebook, but still useful - just_tools_example.py
GPT5 option presets
Dependencies ppdates (litellm 1.75.6 notably)
Rare bug with functions having a parameter named 'title' - fixed.
Support for mcpServers configs inputs to instantiate an MCP tools
inits and PEP420 fix once again, it keeps happening.

MCP Bugfixes

Updated everything to latest&greatest
Had to downgrade langfuse to before v3. The alleged fix just doesn't work.
Fixed a major bug with MCP client loops mismatch witch caused a leak in tasks, unneeded reconnects an other overhead. Was visible as warnings about pending tasks killed.
Breaking change in return type in fastmcp, fixed compatibility
GROQ introduced some new bugs and apparently structured_output + tool_call combo on META v4 LLaMAs is now not working Can't do much about this, removed from tests.
longstanding intermittent problems with poetry and metapackages, added init to address, hopefully I'll never see these import errors again.

Release Notes: Complete Tools Support Framework

We're excited to announce a major milestone in our tools support framework. This release delivers comprehensive tooling capabilities that enable seamless integration of various tool types within your agents.

🎉 What's New

Complete Tool Type Coverage

Our framework now supports all major tool categories:

Stateless Tools: Pure functions without dependencies on external state
Static Methods: Class-based static methods with full type safety
Stateful Tools: Instance methods supported as transient tools (automatically excluded from serialization)
MCP Tools: Model Context Protocol tools with support for both STDIO and SSE modes via FastMCP integration
Google Built-in Tools: Native support for Google's built-in search and code execution capabilities
Prompt Tools: Pre-configured tools with predefined inputs, ideal for listings and templated operations

Universal Serialization Support

All tool types, except instance methods, can be seamlessly:

✅ Serialized to and deserialized from JSON
✅ Stored in agent YAML configurations
✅ Persisted and restored across sessions

Flexible Execution Models

Every tool type supports both:

Synchronous execution for immediate results
Asynchronous execution for non-blocking operations

🚀 Key Benefits

Unified API: Single, consistent interface across all tool types
Type Safety: Full TypeScript/Python type annotations and validation
Configuration-Driven: Define tools declaratively in YAML configs
Transport Agnostic: MCP tools work seamlessly across different transport layers
Developer Experience: Intuitive APIs with comprehensive error handling
