TM1 IDE — The Complete IDE for IBM Planning Analytics / TM1

Author: flameY3T1

Turn VS Code into a full TM1 development environment.

Write TI processes and rules with real autocomplete, a configurable linter and a server-backed compile check. Browse and edit cubes and dimensions visually — native views and MDX alike.

Watch threads, read the message log, manage security and chores.

One tree, as many servers as you like.

What you get

• Cube Viewer — native views and MDX alike: drag-and-drop pivot, write-back, spreading, suppress zero, save views, paged loading for huge cubes.
• Dimension Browser & Editor — read a dimension as a tree or as a set, native or MDX; edit it with drag-and-drop hierarchies, multi-edit attributes, usage-check before delete.
• TI process editor — 4-section Monaco editor with syntax highlighting and autocomplete, debugging with breakpoints, and a server compile-check on save.
• Configurable linter + formatter — per-server rule sets and severity. Strict on Prod, relaxed on Sandbox.
• Rule editor — syntax highlighting, context-aware autocomplete ([→dims, DB(...)→cubes/elements, !Dim→vars), builders for DB() and [] references, Qualify Elements in dimension order, CheckRules on save.
• MDX Runner — F5 to run, autocomplete, live validation, pivoted results, history, cell-limit guard.
• Operations — threads, message log, security, chores, live from the tree.
• Analysis — search and replace across processes, unify variables, normalise naming and casing, object usage, call graphs, cube statistics, TI runtimes read from the message log.
• Git mirror — processes and rules as files, drift detection, Pull / Push / Diff. Server stays source of truth.
• TI test framework (beta) — record a process run, replay it offline. Recording deploys and runs a rewritten copy on the server and changes server state: Dev/Sandbox only, at your own risk.

Pair it with the TM1 MCP Server

From the same author: the TM1 MCP Server lets the AI tool of your choice (Claude, Cursor, Copilot, …) talk to TM1 directly — process logic, rule debugging, MDX, model analysis, right next to this IDE.

npm install -g tm1-mcp-server

Getting started

1. Install — Extensions (Ctrl+Shift+X) → search "TM1 IDE" → Install → fully restart the IDE.
2. Add a server — TM1 Explorer icon → Add Server. A guided quick-pick walks every field; passwords go to the OS keychain, never plain text.
3. Open something — cubes, dimensions, processes, chores, views, files, threads, message log and the MDX Runner hang under each connected server. Several connections stay open at once.

Now navigate through the TM1 IDE and have fun. 🎉

Shortcuts

Debugging a process needs EnableTIDebugging=T on the server.

Security & privacy

Built for corporate environments:

• No telemetry — nothing leaves your machine.
• Credentials in the OS keychain — never in plain text or config files.
• Direct connection only — your machine straight to your TM1 servers. No third-party endpoints.
• Per-profile SSL — disable self-signed verification only on trusted networks.
• Disabled in Restricted Mode — because it can deploy and run TI code. Mark the folder Trusted to use it.
• Remote-ready — runs as a workspace extension (Remote-SSH / WSL).

Acknowledgments

Thanks to the best TM1 community in the world — at Deutsche Bahn — for the inspiration, and for finding the bugs. This exists because of you.

And a tip of the hat to linti, the inspiration behind this extension's linter. 😉
