Microsoft Managed Apps is a project for building custom web applications with React, TypeScript, and Vite, and it provides Microsoft's official templates and development tooling. Developers use its SDK, CLI, and Vite plugin to create and manage these applications. Its catalogue add-ons help AI coding agents build Microsoft Managed Apps.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00055 | $0.03490 |
| Opus 5.5 | $0.00022 | $0.01396 |
| Sonnet 5.5 | $0.00011 | $0.00698 |
| Haiku 4.5 | $0.00006 | $0.00349 |
Grade A, and why
add-data-source scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 276 lines — stays where its author put it; the contents beside it link to each section on GitHub.
📋 Shared Instructions: shared-instructions.md — Cross-cutting concerns.
Reference: connector-reference.md — Inline connection creation, Grep-first for large generated files.
Reference: allowed-actions.md — Shared connections must declare allowedActions before deploy (Step 4).
Add Data Source (Canonical)
This is the single implementation for all connector-binding skills.
Delegation model:
- Specialized
/add-*skills (e.g.,/add-office365,/add-workiq) delegate to this skill with presets - If this skill is called from a wrapper, do not delegate back
- If this skill is called directly, complete the workflow without delegation
After the connector is added:
- If invoked via a specialized skill → Refer to that specialized skill's documentation for usage patterns (it was already provided)
- If invoked directly → Identify which specialized skill matches your use case and refer to its documentation for:
- Correct import paths for generated services
- Best practices for using the connector
- Common patterns and implementation examples
- Error handling guidance
This ensures developers have complete context for implementing features, not just adding the connector.
Workflow
- Verify workspace + auth.
- Resolve
api-id(discover viams connector listif the user didn't supply one),mode, and required arguments. - Run the matching
ms app add ...command. - Check for a shared connection and declare
allowedActionsif so. - Run
npm run build. - Record the binding in
memory-bank.mdif present.
Step 1: Verify Project + Env
test -f ms.config.json || { echo "Not in a Microsoft App workspace."; exit 1; }
BIN=ms
$BIN auth status
Step 2: Resolve Inputs
Collect:
api-id(required — see resolution order below). Passed to the CLI via--connector <api-id>.mode=action|table(controls the--asflag). There is noproceduremode — binding a specific SQL stored procedure is not exposed by the current CLI (see note below).connection-id(optional interactive, required for non-interactive where applicable)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

add-data-source is a skill published in the GitHub repository microsoft/managed-apps (36 stars, last pushed 3d ago), licensed MIT. It adds 55 tokens to every session and 3,490 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
