* perf: defer MCP SDK import by fixing import path in agent/core.py - Change 'from crewai.mcp import MCPServerConfig' to direct path 'from crewai.mcp.config import MCPServerConfig' to avoid triggering mcp/__init__.py which eagerly loads the full mcp SDK (~300-400ms) - Move MCPToolResolver import into get_mcp_tools() method body since it's only used at runtime, not in type annotations Saves ~200ms on 'import crewai' cold start. * perf: lazy-load heavy MCP imports in mcp/__init__.py MCPClient, MCPToolResolver, BaseTransport, and TransportType now use __getattr__ lazy loading. These pull in the full mcp SDK (~400ms) but are only needed at runtime when agents actually connect to MCP servers. Lightweight config and filter types remain eagerly imported. * perf: lazy-load all event type modules in events/__init__.py Previously only agent_events were lazy-loaded; all other event type modules (crew, flow, knowledge, llm, guardrail, logging, mcp, memory, reasoning, skill, task, tool_usage) were eagerly imported at package init time. Since events/__init__.py runs whenever ANY crewai.events.* submodule is accessed, this loaded ~12 Pydantic model modules unnecessarily. Now all event types use the same __getattr__ lazy-loading pattern, with TYPE_CHECKING imports preserved for IDE/type-checker support. Saves ~550ms on 'import crewai' cold start. * chore: remove UNKNOWN.egg-info from version control * fix: add MCPToolResolver to TYPE_CHECKING imports Fixes F821 (ruff) and name-defined (mypy) from lazy-loading the MCP import. The type annotation on _mcp_resolver needs the name available at type-check time. * fix: bump lxml to >=5.4.0 for GHSA-vfmq-68hx-4jfw lxml 5.3.2 has a known vulnerability. Bump to 5.4.0+ which includes the fix (libxml2 2.13.8). The previous <5.4.0 pin was for etree import issues that have since been resolved. * fix: bump exclude-newer to 2026-04-22 for lxml 6.1.0 resolution lxml 6.1.0 (GHSA fix) was released April 17 but the exclude-newer date was set to April 17, missing it by timestamp. Bump to April 22. * perf: add import time benchmark script scripts/benchmark_import_time.py measures import crewai cold start in fresh subprocesses. Supports --runs, --json (for CI), and --threshold (fail if median exceeds N seconds). The companion GitHub Action workflow needs to be pushed separately (requires workflow scope). * new action * Potential fix for pull request finding 'CodeQL / Workflow does not contain permissions' Co-authored-by: Copilot Autofix powered by AI <62310815+github-advanced-security[bot]@users.noreply.github.com> --------- Co-authored-by: Joao Moura <joaomdmoura@gmail.com> Co-authored-by: Copilot Autofix powered by AI <62310815+github-advanced-security[bot]@users.noreply.github.com>
