Security Policy

English | Turkce

Scope

mcpbase is a stdio-first MCP base library. The codebase exposes security helpers, deny-by-default guards, and examples for derived servers, but each derived server remains responsible for its own threat model and deployment posture.

Reporting a vulnerability

  • Do not open a public GitHub issue for undisclosed vulnerabilities.
  • Prefer a private maintainer contact path if you already have one.
  • If no private contact is known, maintainer confirmation is required for the preferred reporting channel.
  • Include impact, affected version, reproduction steps, and any relevant guard or config assumptions.

Repository security model

  • Risky behavior should be protected with feature flags, command allowlists, or path allowlists.
  • MCP logging must stay on stderr so protocol traffic is not corrupted.
  • New config fields should be documented together with code changes.
  • New tools with filesystem or command execution behavior should ship with guards and tests.

Supported versions

Formal version support windows are not documented in the repository. Unless maintainers state otherwise, treat the latest published release as the only confirmed security maintenance target.
