ctxai

stdio

A version-aware MCP server that prevents AI coding hallucinations by validating suggestions against your actual installed packages.

Install

pip install |

get_project_context Scans your project root and returns a structured fingerprint of every installed package and its exact version
validate_suggestion Takes AI-generated code and the fingerprint from get_project_context, then runs three validation layers to check for missing packages, hallucinated methods, and suggests closest real alternatives
check_package_safety Checks every new package the AI suggests installing against three safety layers: existence on npm/PyPI, typosquat detection, and trust level
get_package_docs Fetches live metadata from npm or PyPI for a specific package version, used by the LLM to self-correct after a hallucination is detected
