MCP
Connect Claude or ChatGPT to these values, your league and the trade calculator.
Endpoint
https://stage.charted.gg/mcp
Paste this into your assistant's connector settings.
Claude
- Open Settings → Connectors on claude.ai, in the desktop app, or on mobile.
- Choose Add custom connector and paste the endpoint above. Leave the client id and secret blank — the server hands them out itself.
- Claude opens an authorization screen. Enter the passphrase set when the server was deployed.
- Start a conversation and the four tools below are available.
Works on every Claude surface that supports connectors, so a connector added on the web is there on your phone too.
ChatGPT
- On the ChatGPT web app, open Settings → Apps → Advanced settings and turn on Developer mode. It is available on Plus, Pro, Business, Enterprise and Education plans.
- Back in Settings → Apps, add a connector and paste the endpoint above.
- Authorize when prompted, with the same passphrase.
- In the composer, open the Developer mode tool and tick this app for the conversation.
ChatGPT reaches MCP servers through developer mode rather than the regular connector directory, so it is a per-conversation choice rather than always on.
What it can do
get_values- The board: our league-adjusted Value, the league-independent Blended value, and each source's own number.
get_league- Settings, where the starter and roster lines fall, and every team with its record, odds and picks.
add_note- Remember something about a league-mate — what they will not trade for, how they negotiate — so it shapes the next trade search.
remove_note- Forget a note that is wrong or out of date.
evaluate_trade- A trade of two to four sides, priced on both horizons, with roster crunch, lineups and odds.
search_assets- What a name refers to, and what it is worth. Asks rather than guessing when a name is ambiguous.
Values are scarcity-adjusted for a specific league, so the same player is worth different amounts in different ones. Ask about a trade in plain language — the tools take player names, and will ask which player you meant rather than guess.
Signing in
The connection is OAuth, and the server issues its own tokens. Your assistant registers itself, so there is nothing to create in advance and no key to paste — the one thing you need is the passphrase, which is set when the server is deployed and is deliberately not shown on this page.
Nothing private sits behind the endpoint: the values are the same ones this site serves to anyone. The sign-in is there because pricing a trade runs thousands of simulated seasons, and that is worth spending on your own questions rather than a stranger's.
