Coartifex

A gacha relic co-pilot built for people and their agents. Score relics, plan builds, decide what to farm next, and stay in control of every save.

WebMCP: checking...

Use it with your agent

Coartifex is WebMCP-first. Open this page in ChatGPT's in-app browser, then just ask. Paste a relic screenshot and say "read this and add it", or "score this for Acheron", "suggest a build", "what should I farm next". Your agent drives the page's tools; nothing saves without your approval.

Quick seed so you can see the tools work.

Import your account

Paste your Honkai: Star Rail UID and this pulls the relics on your showcased characters, straight from the game's public profile via a small proxy. Nothing is uploaded to us.

1. Pick your game

Two demo profiles ship built in. Your pick only changes the scoring rules.

Advanced: import a custom game profile (JSON)

2. Add a relic

The fast way is in ChatGPT: paste a screenshot and ask the agent to add it. If you'd rather do it by hand:

Slot
Set
Main stat
Nickname (optional)

Substats

Rolled bonuses on the piece, e.g. crit damage 22.4.

3. Your inventory

Every piece is scored the moment it lands. The grade is for its best-fit character.

4. Advisor

Ask for a build or a farming plan. An agent in ChatGPT can run these exact same two actions.

Character
Current pity
Pulls saved

Results and reasoning appear here.

5. Saved loadouts

Approved saves land here, one per character.

6. Session receipts & agent gate

Every tool call is logged as a receipt, and mutating actions only happen after your approval. Turn on the lock to revoke the agent's ability to save entirely.
