* chore: add example server pretty print JSON RPC for transparency
* updated telemetry module
* chore: agent side tel - langchain adapter - client tel
* server side tel:
* update API reference
* python transports and primitive reports are publishes only if not skipped
* remove wrongly generate files
* properly typed middleware
* remove examples
* feat(docs): add middleware and session management documentation
- Introduced new documentation for middleware, detailing hooks, minimal examples, and best practices for integrating middleware in MCP servers.
- Added a session management guide explaining session ID handling, usage patterns, and examples for managing per-client state in MCP servers.
- Updated to include links to the new middleware and session management pages.
* generate docs
* remove few events
* adapter tel
* adapter tel
* api ref docs update
* google adapter fix
* fix version
* fix event naming
* server example is streamable and echo tool fix
* removed initialize middleware hook, initialize requests are not passed thorugh normal handlers
* api ref
* beta on middleware
* 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
