BC Observatory

An outside-the-box way to see all of Microsoft Dynamics 365 Business Central at once: official docs, source code, Microsoft's guidelines, YouTube sessions and community blogs, woven into one cross-referenced knowledge base that AI agents can use as a source of truth and humans can travel through like a galaxy.

Site: https://waldo1001.github.io/waldo.BCObservatory/ (GitHub Pages, rebuilt every night) About the project, who it is for: https://waldo1001.github.io/waldo.BCObservatory/about/ · The MCP server and the plugin, what to ask, how to install: https://waldo1001.github.io/waldo.BCObservatory/mcp/ Status: milestone M3 (content flowing nightly: Learn topic hubs, 16k AL object pages for BC28-30, 22 localizations, roadmap features, videos, community posts). Machine-generated pages are badged unreviewed until Opus reviews them.

Use it from an agent

claude mcp add bc-observatory -- npx -y bc-observatory@latest      # MCP server (packages/mcp)
claude plugin marketplace add waldo1001/waldo.BCObservatory          # Claude Code plugin: MCP + bc-lookup, bc-whats-new, bc-localization, bc-grounding

Source bodies and the call graph: bc-code-atlas by Stefan Maron (MIT), connected by the plugin.

To run the server from a checkout instead: claude mcp add bc-observatory -- env BC_OBSERVATORY_LOCAL=$PWD node --import tsx packages/mcp/src/server.ts. Without any install: llms.txt, GitMCP and DeepWiki (badges above).

What it is

• Overlay, not mirror. Microsoft Learn stays the canonical documentation. BC Observatory builds hub pages per topic, feature, AL object and localization that summarize and deep-link to Learn articles, the actual code (microsoft/BCApps and the version history), BCQuality rules, videos (with timestamps) and blog posts.

• Agents first. Every page is markdown with strict frontmatter, every index is JSON, llms.txt exists per section, and npx bc-observatory is an MCP server over the same files. GitMCP and DeepWiki work out of the box.

• A galaxy to travel. Domains are systems, hubs are stars, sources orbit the hub they describe, localizations are constellations drawn over the W1 sky, and this week's changes light up. Authors get a flight path showing where their blog hooks into BC.

• Change radar. What changed in BC this week: docs commits, code diffs per object and per version, deprecations, roadmap items, new videos and posts, with a weekly digest and RSS.

• Honest by construction. Deterministic extraction first; language models (Haiku for facts, Sonnet for prose, Opus for review) only on deltas; every claim carries evidence; every page shows its trust tier and review state.

How it runs

Nightly, on a Mac Mini registered as a self-hosted GitHub Actions runner, on a Claude subscription (no API keys), inside a fixed budget window, newest content first. See docs/PLAN.md for the architecture and docs/RUNBOOK.md for operations.
