Private beta — Dynamics 365 F&O

Your AI assistant finally
knows your X++

Copilot hallucinates X++ methods. It can't see your custom models, your ISV packages, or 700,000 objects of standard code. XppAtlas indexes your entire D365 F&O codebase and serves it to any AI agent over MCP — without your code ever leaving your network.

agent session — with and without XppAtlas
# Without:
✗ agent writes  CustTrans::findRecId(...)   // method doesn't exist — build fails

# With XppAtlas:
→ check_symbol("CustTrans", "findRecId")
✓ exists: false · nearest: findFromVoucher, find
✓ agent writes  CustTrans::findFromVoucher(...)   // compiles first try

How it works

One server for the team, one folder per developer. No cloud upload, no per-seat agents, no IDE lock-in.

Server indexes the platform

The XppAtlas server holds a semantic + full-text + relation-graph index of standard Microsoft models for your exact D365 version — built once, shared by the whole team.

Your code stays local

Each developer indexes their own custom and ISV models on their machine. Customer code is never uploaded anywhere — queries against it run locally.

Agents stop guessing

Claude, Copilot, Cursor — any MCP-capable agent gets search, call graphs, extension points, and symbol verification. Hallucinations die at the source.

Built for D365 F&O, not adapted to it

General code-search tools see XML blobs. XppAtlas understands tables, forms, data entities, security artifacts, CoC extensions, and how they reference each other.

✓Anti-hallucination symbol check

The agent verifies a method, field, or enum value exists — including inherited and extension members — before writing code that uses it.

✓Semantic + keyword + graph search

Hybrid retrieval over code meaning, exact names, and the relation graph — posting class to table to form, in one query.

✓Extension-point discovery

CoC targets, delegates, data and form events — ranked, with callers and impact radius, so changes land where Microsoft intended.

✓Version-exact standard index

Your project runs 10.0.47? The index matches 10.0.47. New Microsoft release — switch the version, keep working.

✓Model-level access control

Hide vendor models from contractors. RBAC per model, with relation suppression so hidden code doesn't leak through cross-references.

✓Works with your agent

MCP standard: Claude Code, GitHub Copilot (VS 2022 & VS Code), Cursor, and anything that speaks MCP. No proprietary IDE plugin.

Your code never leaves your network

Custom and ISV models are indexed and queried locally on each developer's machine. Embeddings are computed with local models — no OpenAI, no cloud APIs touching your source. Air-gapped LAN deployments supported. The only thing the team server holds is Microsoft's standard code, which is identical for every D365 customer.

Early access

We're onboarding a small number of pilot teams. Pilots run free, get direct support from the team building it, and lock in early pricing.
