* Add docs
* feat(python/cli): improve create-mcp-use with rich UI, dependency install, and telemetry
- Use rich for colored output, spinner, and panel for get-started instructions
- Add ASCII logo matching the TypeScript CLI
- Prompt user to install dependencies after scaffolding (detects uv/pip)
- Add --install and --no-install flags for non-interactive use
- Capture install output to keep terminal clean
- Add CreateMCPUseEvent telemetry to track CLI usage
- Fix starter template pyproject.toml hatch build config for installability
* feat(python/server): auto-retry next available port when default is in use
Add port availability checking before starting uvicorn. When the
requested port is occupied, the server automatically tries the next
port (up to 10 retries) instead of crashing.

* chore: update imports
* refactor(mcpagent): update agent creation logic and imports
- Replaced `create_tool_calling_agent` with `create_agent` for improved agent instantiation.
- Simplified the `_create_agent` method by removing the `AgentExecutor` and directly returning the created agent.
- Adjusted type annotations for `_agent_executor` to initialize as `None` instead of using a union type.
* feat(mcpagent): migrate to LangChain 1.0.0 and simplify agent methods
- Updated MCPAgent to utilize LangChain 1.0.0's `create_agent()` for improved agent instantiation.
- Introduced new methods `astream_simplified()` and `run_v2()` that leverage the built-in `astream()` for internal agent loop handling.
- Retained legacy methods `stream()` and `run()` for backward compatibility with manual execution.
- Enhanced documentation to reflect changes and provide clearer usage examples.
* feat(mcpagent): implement dynamic tool updates during agent execution
- Enhanced the MCPAgent to support dynamic tool updates when using server_manager mode.
- Implemented logic to check for tool changes before and during execution, allowing for immediate updates and safe restarts.
- Introduced a maximum restart limit to prevent infinite loops during tool updates.
- Updated documentation to reflect the new behavior and usage of dynamic tool management.
* refactor(mcpagent): clean up imports and streamline logging
- Removed unused imports and organized existing ones for better clarity in `mcpagent.py`.
- Simplified logging statements for consistency and improved readability.
- Enhanced the overall structure of the code by eliminating unnecessary whitespace.
- Updated unit tests to reflect changes in imports and ensure compatibility with the refactored code.
* feat(mcpagent): enhance agent execution with step tracking and middleware
- Introduced `ModelCallLimitMiddleware` to enforce a maximum number of model calls during agent execution.
- Updated the `_consume_and_return` method to return a tuple of the final result and the number of steps taken.
- Enhanced telemetry tracking to include steps taken and execution time for better performance insights.
- Simplified agent creation logic by integrating middleware directly into the `create_agent` function.
- Improved logging for agent execution details, including steps and tool usage.
* fix(mcpagent): add null check for node output messages extraction
- Updated the MCPAgent to include a null check for `node_output` before attempting to access the "messages" key, preventing potential errors during message extraction.
* minor
* feat(mcpagent): filter out ToolMessage from history
- Updated the MCPAgent to exclude ToolMessage instances from being added to the message history, ensuring that only relevant messages are recorded.
- This change helps maintain a cleaner history by avoiding intermediate tool execution details.
* fix(mcpagent): set max_steps assignment
* ruff
* docs
* e2e tests for agent
* key in tests
* fix manager test and split ci tests
* telemetry off for tests
* fix server manager test
* feat(mcpagent): delegate query streaming to remote agent in remote mode
- recreated functionality to the MCPAgent to yield results from a remote agent when operating in remote mode, enhancing the agent's capability to handle queries efficiently.
* fix: agent unit tests
* Print inputs
* rollback, wrong repo
* fix streaming output
* stricter streaming test
* pass observability callbacks
* fix tests mock
