Technical Answer Validator MCP server

Technical Answer Validator

<!-- mcp-name: io.github.Christofer566/technical-answer-validator -->

A tiny, deterministic answer review tool for AI agents, available over MCP stdio and as a REST API. Each caller supplies the concepts, accepted synonyms, numeric requirements, and answer text for a single evaluation. It does not include a question bank or answer corpus.

This is an assistive practice tool, not an official certification exam grader. Keyword matching can miss semantically correct paraphrases and can accept misleading surface matches. Users should review the supplied rubric and every result.

Run locally

Python 3.10+; the REST server uses the standard library. The MCP adapter uses the official Python SDK 2.2.0.

$env:TAV_API_KEY = "replace-with-a-long-random-secret-at-least-24-characters"
python -m tav_api

The service listens on 127.0.0.1:8080 by default. To change it, set TAVHOST and TAVPORT. Local single-key mode refuses to start without a TAVAPIKEY of at least 24 characters. For deployment, create a distinct key per caller with python scripts/createapikey.py CLIENTID and configure TAVAPIKEYS as a JSON object mapping each client ID to the generated SHA-256 digest. Store the one-time raw key with that client; do not store or commit it in this repository. When TAVAPIKEYS is set, it takes precedence over TAVAPI_KEY.
