MCP server address
https://wesplit.fun/mcpClaude Code
claude mcp add --transport http wesplit https://wesplit.fun/mcpCodex CLI
codex mcp add wesplit --url https://wesplit.fun/mcpWhat the assistant can see and do
Only what you allow when you connect: your groups, their members, expenses and balances and, if you leave changes on, adding, editing and deleting expenses, recording repayments and creating groups. It works only in groups you belong to. WeSplit.Fun never moves money: a recorded repayment is a note in your group’s ledger.
You stay in control
Your assistant asks before it changes something, depending on its settings. Every change appears in the group’s activity under your name, and other members are notified as usual. A deleted expense can be restored from its page.
Disconnecting
Open your profile and choose Disconnect next to the app. Its access ends immediately. You can also remove WeSplit.Fun in your assistant’s settings.
Privacy
The assistant receives the group information it asks for so it can answer you, and its provider handles that information under its own privacy policy. WeSplit.Fun does not receive your chat history. We keep a record of the connection and only hashes of its access tokens.
