Product — Bridge Town
Bridge Town is a version-controlled financial planning platform built for AI-assisted FP&A. This page describes what the product does and how it’s structured.
What Bridge Town is
Bridge Town is a financial modeling substrate for teams using AI agents. It provides:
- Project-based storage — each financial model is a project with a full Git-backed version history
- Sandboxed execution — models run in isolated Docker containers; no outbound network, no host filesystem access
- MCP-native interface — Claude, Codex, Cursor, or any MCP-compatible agent can read, write, and run models using the Bridge Town MCP server
- Data connectivity — attach Google Sheets, CSV files, or other data sources; DuckDB runs queries in-process without a data warehouse
- Dashboards — one-call HTML dashboard generation from any model run; share a file or a hosted link
Core capabilities
Models
Financial models in Bridge Town are real Python files, not spreadsheet cells. Every formula is auditable, every assumption is explicit, and every change is a diff.
- Version history for every model file
- Branch and merge workflow: propose a change, review the EBITDA delta, approve and merge
- Impact diffs: see the financial delta before any change lands
Scenarios
Run alternative assumptions without breaking the baseline. Scenarios are model branches — you can compare any two states side by side, attribute the variance to specific drivers, and roll back to any prior snapshot.
Audit log
Every tool call and model run is logged to an append-only audit trail. Fields include who ran what, when, against which data snapshot, and what the output was. The audit log is exportable and queryable.
Who it’s for
Bridge Town is built for senior FP&A analysts and finance teams who want AI agents to do useful work — not just generate text — in their models.
It is not a BI tool, a spreadsheet replacement, or a chat interface. It is the infrastructure that makes AI-generated financial models trustworthy, versioned, and collaborative.
