It is distributed as splitwise-mcp on npm, filed under Other by this index, and declares 2 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; [the index's current counts](/stats) put this record in context.\n\n## Using io.github.chrischall/splitwise-mcp in Claude, Cursor, Gemini CLI, Cline, or Zed?\n\nMCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and **HOLDs the call** when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use **Install this server** for that).\n\nRewrites your MCP host config so each server launches behind the gate.
