Introducing bc-code-atlas: Real BC Source for Coding Agents, Not a Guess
bc-code-atlas is an MCP server, with a hosted instance and a self-host option, that lets AI agents or humans search Business Central Base Application source across versions and country variants. It combines semantic search, an exact call/subscribe/extend graph built on graphify-al, exact-source lookup tools, and version and country diffing so every hit can be checked against the real AL file. The author notes it is young: the public instance has no real authentication and has had outages.

Key points
- Addresses AI agent hallucination by ensuring all code results are verifiable against actual BC source files
- Offers semantic search for behavior-based discovery and exact structural graph analysis for precise call tracing
- Supports diffing symbols across BC versions and country variants to track real code changes
- Built on graphify-al for AL language parsing and tree-sitter-al integration
