Enables LLM agents to answer questions about Darshan I/O logs by first opening a log and then retrieving exact, tool-computed numbers: canonical per-concern cards (volume, bandwidth, request sizes, metadata, rank balance, Lustre, DXT, verdict), an outline/search/get interface over a two-layer schema, and exact arithmetic, so answers are retrieved rather than estimated.

Provides investigation tools for Cloudflare CCF data in Microsoft Sentinel, enabling security posture assessment, threat detection, and IP reputation analysis through customizable MCP tools.

A read-only MCP server exposing GPON access-network tools for inventory, status, configuration diff, and alarms, enabling a LangGraph agent to audit ONT provisioning against a golden baseline. It runs against a simulated network and enforces read-only constraints at multiple levels.
