Questions

What is the KQL MCP server?

Kusto and Log Analytics MCP server help you execute a KQL (Kusto Query Language) query within an AI prompt, analyze, and visualize the data.

Is KQL safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does KQL need?

It reads MCP_KQL_AUTH_CHECK_TIMEOUT_SECONDS, MCP_KQL_AUTH_LOGIN_TIMEOUT_SECONDS, MCP_KQL_AUTH_MODE and MCP_KQL_AUTH_READY_TIMEOUT_SECONDS from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does KQL run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on PyPI as mcp-kql-server.

How current is this page?

The grade is for one exact copy of the source (197e17ccb24e), read on 2026-10-09. The repository is watched and re-audited when it changes.
