- Add errors.Join to return aggregated error when all enabled MCP servers fail
- Track enabled server count separately from total configured servers
- Return error only when all servers fail, not for partial failures
- Improve logging with accurate server counts (enabled vs connected)
- Maintains fault tolerance: partial failures don't stop initialization
Implement comprehensive MCP support with stdio/HTTP/SSE transports, environment variable configuration (env and envFile), custom headers, tool registration, and automatic resource cleanup. Includes full test coverage and VSCode-compatible configuration.
- Added pkg/mcp/manager.go for server lifecycle management
- Added pkg/tools/mcp_tool.go for tool wrapping
- Integrated into agent loop with cleanup
- Support for envFile loading (.env format)
- Headers injection for HTTP/SSE authentication
- Example configs for filesystem, github, brave-search, postgres
