About Klarion

Klarion is an MCP server published by the GitHub account 0x1Adi. Secret scanning for AI agents: rules and entropy find candidates, a model decides which are real.

It runs on your own machine: your AI client starts it from the MCP bundle package klarion-mcp-v0.4.3.mcpb at version 0.4.3.

It asks for one secret: ANTHROPIC_API_KEY. Give it a key with the least access that still works.

Version 0.4.3 was published on 20 September 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on registry metadata: 4 pass, 0 warn, 0 fail, 3 info. How we check.

What it asks for

VariableRequiredSecretDescription
ANTHROPIC_API_KEYNoYesOptional. With a key Klarion adjudicates candidates itself; without one it hands them to the calling agent to judge.
