fabric-rest-api

fabric-rest-api is a skill for Claude Code from wardawgmalvicious/agent-config. It costs 128 tokens per session (7,181 once invoked), scanned A, original, MIT.

A guide to calling Microsoft Fabric's web API, the interface programs use to list and change Fabric resources. It covers paging through large result sets and waiting for operations that finish later.

In plain words
What is it for?
Use it to find workspaces and items, search across accessible Fabric resources, call item-specific endpoints, and poll long-running operations until they finish.
Why use it?
It avoids incomplete listings and incorrect handling of requests that return before the actual work is done.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

fabric-rest-api scanned grade A with 1 finding 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 10d 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.

Fabric REST API patterns

Base URL: https://api.fabric.microsoft.com/v1

Three jobs have a reference of their own: read it before answering one. The rest of this file is the REST API itself.

The job Read first
A token or its audience, az login or az rest, a TDS connection, or what authorizes a service principal auth.md
The Fabric CLI, fab: paths, commands, fab auth, fab api cli.md
An error code, error text or symptom, from any Fabric surface gotchas.md, whose index names the reference or skill that owns the fix

Finding Workspaces and Items

  1. List workspaces: GET /v1/workspaces → paginate with continuationToken
  2. Find by name: iterate results until displayName matches
  3. List items in workspace: GET /v1/workspaces/{wsId}/items?type={ItemType}
  4. Type-specific endpoints return extra properties (connection strings, etc.): GET /v1/workspaces/{wsId}/{lakehouses|warehouses|notebooks|semanticModels|...}
  5. Cross-workspace discovery (no wsId in path): POST /v1/catalog/search with { "search": "Sales Revenue", "pageSize": 50, "filter": "Type eq 'Lakehouse'" } → permission-trimmed items (each with id GUID + workspaceId) across your whole accessible estate, by catalog metadata (name/description/workspace name). OneLake Catalog Search API (Preview, March 2026); same capability as the fab find CLI verb (cli.md) and the Fabric Core MCP server's search_catalog tool.

Sensitivity Labels on Item Responses

As of March 2026 GA, List Items / Get Item / Update Item responses include a sensitivityLabel property on the Item object when the item has a Purview information-protection label applied:

{
  "id": "34fa05fc-e7ba-435a-b1ab-63534b6aa4f9",
  "displayName": "PDF_Env",
  "type": "Environment",
  "workspaceId": "2ae4b0b9-895b-4676-bfcd-125b1f20e34d",
  "sensitivityLabel": { "sensitivityLabelId": "4922deb9-fe99-4f4f-971c-9bdf556ec6a9" }
}

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.
