microsoft/mcp is a repository of Microsoft’s Model Context Protocol server implementations, which let AI applications connect to data sources and tools through a shared client-server interface. It supports Microsoft MCP server contributors and the catalogue entries are add-ons for working with these servers.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00103 | $0.03560 |
| Opus 5 | $0.00051 | $0.01780 |
| Sonnet 5 | $0.00021 | $0.00712 |
| Haiku 4.5 | $0.00010 | $0.00356 |
Grade A, and why
azurebackup-add-tool 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 — 395 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add a New Tool to Azure Backup MCP
Purpose
Step-by-step workflow for adding a new command to the Azure Backup MCP toolset, ensuring it passes all validation gates before PR submission.
When to Use
- Adding a new
azmcp azurebackup <group> <operation>command - Extending an existing command group (vault, policy, protecteditem, etc.)
- Adding a new command group (security, compliance, etc.)
Prerequisites
.NET 10 SDKinstalled (seeglobal.json)- Azure authentication configured (
az login/Connect-AzAccount) - Repository cloned with
upstreamremote pointing tomicrosoft/mcp - Branch created from
upstream/main
Procedure
Phase 1: Implementation
Follow /.github/skills/add-azure-mcp-tools/SKILL.md as the authoritative guide.
The Azure Backup toolset lives in tools/Azure.Mcp.Tools.AzureBackup/.
1a. Create Option Definitions
File: src/Options/{Group}/{Resource}{Operation}Options.cs
// Inherit from the appropriate base options class
public class MyNewOptions : BaseAzureBackupOptions
{
public string? MyParam { get; set; }
}
- Use
OptionDefinitions.Common.*for shared options (subscription, resourceGroup) - Use
AzureBackupOptionDefinitions.VaultandAzureBackupOptionDefinitions.VaultTypefor vault options - Add new options to
AzureBackupOptionDefinitionsif reusable across commands - Use
.AsRequired()/.AsOptional()extension methods
1b. Add Service Method
File: src/Services/IAzureBackupService.cs and src/Services/AzureBackupService.cs
- Add the interface method first
- Route to
rsvOpsordppOpsbased on vault type usingResolveVaultTypeAsync - For RSV-only operations, add to
IRsvBackupOperations/RsvBackupOperations - For DPP-only operations, add to
IDppBackupOperations/DppBackupOperations
1c. Implement the Command
File: src/Commands/{Group}/{Resource}{Operation}Command.cs
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.

azurebackup-add-tool is a skill published in the GitHub repository microsoft/mcp (3,643 stars, last pushed today), licensed MIT. It adds 103 tokens to every session and 3,560 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
