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
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00103 | $0.03560 |
| Opus 5.5 | $0.00041 | $0.01424 |
| Sonnet 5.5 | $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 1mo 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 (3,800 stars, last pushed yesterday), licensed MIT. It adds 103 tokens to every session and 3,560 once invoked, about $0.0004 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 2026-08-30.

server-side-calls
Call tRPC procedures directly from server code using t.createCallerFactory() and router.createCaller(context) for integration testing, internal server logic, and custom API endpoints. Catch TRPCError and extract HTTP status with getHTTPStatusCodeFromError(). Error handling via onError option.
mem0-test-integration
Verify a Mem0 integration produced by /mem0-integrate. Runs in the same workspace on the same branch (loose coupling) — installs dependencies, runs the repo's native test suite, then exercises a real end-to-end smoke flow against the user's API key. Produces a scorecard. TRIGGER when: user has just run /mem0-integrate…
