What it does
Msal Client Credentials is an agent skill from AzureAD/microsoft-authentication-library-for-dotnet. Client Credentials Flow for service-to-service (daemon) authentication in MSAL.NET without user involvement
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering Authentication. It works with Microsoft Entra ID and .NET. The repository describes itself as: Microsoft Authentication Library (MSAL) for .NET. The licence is MIT.
When your agent uses it
- Tasks that involve Authentication
Example prompts
- “/msal-client-credentials”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Service authenticates using client credentials (certificate or managed identity)
- Service directly calls authorization endpoint with credentials
- AAD validates credentials and returns access token
- Token cached and used to access APIs as application identity
What it can do on your machine
Read from SKILL.md and the folder at commit 2d15026. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are csharp).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
login.microsoftonline.com
Also links to:
learn.microsoft.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Msal Client Credentials loads about 1.1k tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 273 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Client Credentials Flow Skill
Overview
Client Credentials Flow is used for service-to-service authentication without user involvement. Ideal for daemon applications and background services.
When to Use
- Service-to-service authentication
- Daemon/background applications
- Machine-to-machine communication
- No user context needed
- Automated processes
Flow Steps
- Service authenticates using client credentials (certificate or managed identity)
- Service directly calls authorization endpoint with credentials
- AAD validates credentials and returns access token
- Token cached and used to access APIs as application identity
Agent Actions
Generate Code Snippet
Agent can show code for each credential type:
- Standard Certificate: with-certificate.cs
- Certificate with SNI: with-certificate-sni.cs
- Federated Identity Credentials: with-federated-identity-credentials.cs
Setup Guidance
Reference appropriate credential setup:
Example: Service with Certificate
// Acquire token for service-to-service authentication
public class TokenAcquisitionService
{
private readonly IConfidentialClientApplication _app;
public TokenAcquisitionService(string clientId, X509Certificate2 cert)
{
// For complete example with static token caching, see: with-certificate.cs
_app = ConfidentialClientApplicationBuilder
.Create(clientId)
.WithCertificate(cert)
.WithAuthority($"https://login.microsoftonline.com/{tenantId}/v2.0")
.WithCacheOptions(CacheOptions.EnableSharedCacheOptions) // Enable static token caching
.Build();
}
public async Task<string> GetAccessTokenAsync()
{
var result = await _app.AcquireTokenForClient(
new[] { "resource-uri" })
.ExecuteAsync();
return result.AccessToken;
}
}Error Resolution
Refer to Troubleshooting Guide
Best Practices
- Use Token Caching Strategies - enable static token caching with
.WithCacheOptions(CacheOptions.EnableSharedCacheOptions)for optimal performance - Implement Error Handling Patterns
- Monitor token acquisition using
AuthenticationResultMetadatafor cache hit ratios - Rotate certificates periodically (if using certificate-based auth)
- Use Federated Identity Credentials with Managed Identity for keyless authentication
- For additional caching options and strategies, see Token cache serialization documentation
Explain the Flow
- Credential Submission: Service authenticates directly with AAD using certificate or MI
- No User Involved: Authentication is machine-to-machine only
- Access Grant: AAD validates credentials and issues access token
- Token Caching: Token automatically cached for subsequent requests
- API Access: Token used to call downstream APIs as application identity
Decision Help
Choose Client Credentials if:
- Building daemon/background service
- Service-to-service authentication needed
- No user context involved
- Want simplest flow for automated processes
Avoid if:
- Need to access user-scoped resources
- User consent required
- Need refresh tokens for long-lived sessions
