Sync HashiCorp Vault tools in VS Code

Commit your .vscode/mcp.json to the repository to ensure every teammate uses the same tools. It enforces consistent access to `read_kv_secret` across the entire engineering department. No more manual setup instructions. Everyone gets the same environment, and the team stays aligned on how to handle secrets in the codebase.

Audit security policies in VS Code

Use `list_acl_policies` and `read_kv_metadata` to verify your team's access levels. It brings transparency to your security configuration directly in the editor. You can verify that your policies are applied correctly before pushing code. It makes security reviews a standard part of your development process.

Manage PKI and certificates in VS Code

Issue and revoke certificates without leaving VS Code. Use `issue_pki_cert` to get valid certs for local development services and `revoke_pki_cert` when you are done. It keeps your development environment secure. You can manage the entire certificate lifecycle without needing access to the web UI.

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.

Common questions about HashiCorp Vault MCP in VS Code Copilot

Yes. By committing your mcp.json to the repo, you push the configuration to the whole team. Every developer gets the tools automatically.

Your tokens are managed locally by the MCP client. The server does not persist them, ensuring they stay within your machine's memory.

Use `approle_login` or `github_login` to authenticate your session. This ensures your access is tied to your specific identity and policy permissions.

The server architecture supports standard audit devices like `enable_audit_device`. This allows your IT team to track every action performed through the MCP tools.

Secrets are fetched directly from the Vault API only when you run a tool. They are never stored in your project files or sent to Copilot's training set.
