DLT MCP Server Plugin

A plugin for DLT Viewer that exposes DLT log analysis capabilities via the Model Context Protocol (MCP). It allows AI agents and MCP-compatible clients to query and retrieve information from DLT log files.

Features

• Log Summary – Get message count, file size, timestamp range, duration, and available CTID/APID contexts.
• Search – Filter log messages by CTID, APID, log level, timestamp range, and keyword, with pagination.
• Message Retrieval – Fetch full payload for specific message IDs.
• Selection – Get details of the currently selected message in DLT Viewer.
• Report – Display Markdown reports in the plugin widget with clickable links that navigate DLT Viewer's log window to specific messages.
• History – Browse, view and manage generated reports in a report browser pane. Reports are persisted across sessions and matched against loaded file(s).

• DLT Viewer 2.30.0
• CMake 3.10+
• Boost 1.74+
• Qt 5.14+ / Qt 6 (matching DLT Viewer's build)
