What is Bridger?

Bridger is a public-data operations gateway inspired by the idea of a bridge between data and tools. It handles authentication, parsing, and error handling for public-data APIs on your behalf, and converts them into tools that AI can use directly through the Model Context Protocol (MCP) standard. Any API with an OpenAPI spec becomes an AI tool once registered.

Problems Bridger solves

OpenAPI → MCP conversion

Wiring OpenAPI documents into AI agent tools is hard. Bridger converts them automatically.

Public-data adapter

It handles the complex parts of integration for you — auth keys, coordinate conversion (lat/lon → grid), error-code mapping, and more.

Centralized management

Beyond local MCP servers, manage MCP tools centrally across team and remote environments.
