## Description

This MCP server provides AI assistants with access to the atPlatform ecosystem for decentralized data sharing and storage, built using Dart with the at_client SDK and dart_mcp library for protocol integration. The implementation offers two core tools for listing atKeys with filtering by shared relationships and regex patterns, and retrieving atKey values with binary data detection, plus serves comprehensive atPlatform documentation as markdown resources covering protocol specifications, SDK usage, and authentication workflows. Built with custom logging integration, configurable root domain/port settings, and local atSign key management through the at_onboarding_cli, it serves developers building atPlatform applications who need conversational access to atSign data operations, teams exploring decentralized identity solutions, and AI assistants requiring detailed atPlatform documentation to guide users through implementation and troubleshooting of atSign-based applications.
