About Aletheia Runtime Safety & Scope Creep Filter
Aletheia Runtime Safety & Scope Creep Filter is an MCP server published by the GitHub account vikasny30. Deterministic pre-execution filter that blocks known scope-creep and prompt-injection tool calls
It runs on your own machine: your AI client starts it from the npm package aletheia-mcp at version 0.3.1.
It asks for one secret: ALETHEIA_OPERATOR_SECRET. Give it a key with the least access that still works.
Version 0.3.1 was published on 13 September 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 6 pass, 1 warn, 0 fail, 2 info. How we check.
