TrustPipe

An MCP server that grounds AI answers about a business in real, verified data — sourced live when needed, cached for reliability — instead of stale training data or hallucinated guesses.

Built for the MCP Hackathon. See docs/PLAN.md for the full plan.

Demo

Two runs of the same questions about Obsidian's real pricing, same model:

1. Without TrustPipe connected — baseline (often wrong/uncertain)

2. With TrustPipe connected — grounded, correct, cited answers

Accuracy scored against a written eval set (eval/eval_set.json), not vibes — see eval/run_eval.py.

How it works

get_company_facts(company_name, country_code, topic):

1. Checks a local cache first — instant, reliable, no network dependency.

2. On cache miss, runs live research with a hard timeout, caches the result for next time.

3. On network failure with no cache available, returns an honest "unavailable" status — never a guess.
