The most complete open-source travel planner: real-time collaboration, bookings, budgets, packing lists, journals, offline PWA, SSO and an AI-ready MCP server, with planet-wide place search and routing built in.

Real-time cost tracking and budget management for Claude Code. Zero setup. No Docker. No Grafana. Just install and go.

Lets an AI assistant read and modify a YNAB plan, including viewing budgets, accounts, categories, and transactions, plus creating and deleting transactions. It can run locally over stdio or as a remote Cloudflare Worker connector, with optional read-only mode and category suggestions.

Enables a model to write short Python programs that call a wrapped MCP server's tools as async functions, rather than invoking them one at a time. The program runs in a locked-down Docker sandbox, and every tool call passes through a host-side bridge that enforces an allowlist, schema-validated arguments, call budgets, timeouts and output caps.
