* Add MCP server endpoint for external AI assistants Expose Sure's Assistant::Function tools via JSON-RPC 2.0 at POST /mcp, enabling external AI clients (Claude, GPT, etc.) to query financial data through the Model Context Protocol. - Bearer token auth via MCP_API_TOKEN / MCP_USER_EMAIL env vars - JSON-RPC 2.0 with proper id threading, notification handling (204) - Transient session (sessions.build) to prevent impersonation leaks - Centralize function_classes in Assistant module - Docker Compose example with Pipelock forward proxy - 18 integration tests with scoped env (ClimateControl) * Update compose for full Pipelock MCP reverse proxy integration Use Pipelock's --mcp-listen/--mcp-upstream flags (PR #127) to run bidirectional MCP scanning in the same container as the forward proxy. External AI clients connect to port 8889, Pipelock scans requests (DLP, injection, tool policy) and responses (injection, tool poisoning) before forwarding to Sure's /mcp endpoint. This supersedes the standalone compose in PR #1050. * Fix compose --preset→--mode, add port 3000 trust comment, notification test Review fixes: - pipelock run uses --mode not --preset (would prevent stack startup) - Document port 3000 exposes /mcp directly (auth still required) - Add version requirement note for Pipelock MCP listener support - Add test: tools/call sent as notification does not execute

Sure: The personal finance app for everyone
Get involved: Discord • Website • Issues
Important
This repository is a community fork of the now-abandoned Maybe Finance project.
Learn more in their final release doc.
Backstory
The Maybe Finance team spent most of 2021–2022 building a full-featured personal finance and wealth management app. It even included an “Ask an Advisor” feature that connected users with a real CFP/CFA — all included with your subscription.
The business end of things didn't work out, and so they stopped developing the app in mid-2023.
After spending nearly $1 million on development (employees, contractors, data providers, infra, etc.), the team open-sourced the app. Their goal was to let users self-host it for free — and eventually launch a hosted version for a small fee.
They actually did launch that hosted version … briefly.
That also didn’t work out — at least not as a sustainable B2C business — so now here we are: hosting a community-maintained fork to keep the codebase alive and see where this can go next.
Join us!
Hosting Sure
Sure is a fully working personal finance app that can be self hosted with Docker.
Forking and Attribution
This repo is a community fork of the archived Maybe Finance repo. You’re free to fork it under the AGPLv3 license — but we’d love it if you stuck around and contributed here instead.

Performance Issues
With data-heavy apps, inevitably, there are performance issues. We've set up a public dashboard showing the problematic requests seen on the demo site, along with the stacktraces to help debug them.
