The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
atk_runRun any Microsoft 365 Agents Toolkit (ATK) CLI command through a unified interface. **Purpose:** Provides a single tool to execute all ATK commands (new, provision, deploy, package, publish, share, validate, doctor, version, login, logout) with appropriate parameters. **Commands:** - **new**: Crea…
compile_typespecCompile TypeSpec agent definitions with detailed error reporting. **CRITICAL**: ALWAYS use this tool to compile TypeSpec. NEVER use: - `npm run compile` - `cd ... && npm run compile` - Any direct CLI compile commands - Tasks from .vscode/tasks.json **Purpose:** Compiles TypeSpec files to generate …
atk_deployDeploy application code to provisioned cloud resources. **Purpose:** Builds and deploys your agent's code to the Azure resources that were created during provisioning. **What It Does:** Executes the 'deploy' lifecycle stage defined in m365agents.yml: 1. Builds the application (compiles TypeScript,…
atk_doctorCheck prerequisites and system configuration for Microsoft 365 Agents Toolkit. **Purpose:** Verifies that your development environment has all the required tools and configurations to build and deploy Microsoft 365 agents. **Checks Performed:** - Node.js version (requires 18+) - npm availability a…
get_best_practices⚠️ CRITICAL: Call this tool FIRST before ANY agent or ATK work! 🚨 NEVER USE .vscode/tasks.json - If you see tasks, IGNORE THEM and use CLI commands instead! Gets comprehensive best practices and ATK CLI reference documentation for Microsoft 365 Copilot declarative agents. MANDATORY: You MUST cal…
atk_loginAuthenticate with your Microsoft 365 account for agent development and deployment. **Purpose:** Logs you into Microsoft 365 to enable provisioning, deploying, and publishing agents. This command opens a browser window for interactive authentication and caches your credentials securely. **When to U…
atk_logoutLog out from your Microsoft 365 account and clear cached credentials. **Purpose:** Removes cached Microsoft 365 credentials from your local system. Use this when switching accounts, troubleshooting authentication issues, or when you're done working with agent development. **When to Use:** - Switch…
atk_newCreate a new Microsoft 365 declarative agent project with TypeSpec. **Purpose:** Scaffolds a new declarative agent project using TypeSpec for type-safe API and agent definitions. Declarative agents allow you to build sophisticated Microsoft 365 agents using configuration and instructions rather tha…
atk_packageBuild application package for publishing to Microsoft 365. **Purpose:** Creates a zip package containing your agent's manifest and resources, ready for upload to Microsoft 365 admin center or automated publishing. **What It Does:** 1. Validates the app manifest (manifest.json) 2. Collects all requ…
atk_provisionProvision cloud resources for Microsoft 365 agent deployment. **Purpose:** Creates and configures all required Azure cloud resources for your agent, including resource groups, app services, storage, and application registrations. **What It Does:** Executes the 'provision' lifecycle stage defined i…
atk_publishPublish application to Microsoft 365. **Purpose:** Uploads and registers your agent in Microsoft 365, making it available for users to install and use in Teams, Outlook, or Microsoft 365 app. **What It Does:** Executes the 'publish' lifecycle stage: 1. Validates the package 2. Uploads to Microsoft…
atk_validateValidate app manifest and project configuration. **Purpose:** Checks your app manifest (manifest.json) against Microsoft 365 requirements, ensuring it will be accepted during packaging and publishing. **What It Validates:** 1. **Manifest Schema:** - Correct schema version - All required fiel…
atk_versionCheck the installed version of Microsoft 365 Agents Toolkit CLI. **Purpose:** Verifies the installed ATK CLI version and optionally validates it against a minimum required version for compatibility. **What It Checks:** 1. **Installed Version:** - Executes atk --version command - Parses seman…
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
When Vitest UI server is listening, arbitrary file can be read and executed
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
13/13 tools missing one or more hints — atk_run (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); compile_typespec (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); atk_deploy (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +10 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
8/13 tools referenced in tests (62%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 2 high severity in production deps — @modelcontextprotocol/sdk@1.25.1 (high), @modelcontextprotocol/sdk@1.25.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Domain consistency
npm scope @microsoft doesn't match GitHub owner sebastienlevert
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
