Frequently asked questions

What is the HashiCorp Vault MCP server?

The HashiCorp Vault MCP server is an Security Model Context Protocol server that lets Claude Code, Cursor, Windsurf, VS Code with Copilot, and other MCP-compatible AI agents read and write Vault secrets and manage auth methods for secure secret delivery. It exposes HashiCorp Vault's capabilities as tools the AI can call directly from your editor or CLI.

How do I install HashiCorp Vault MCP with Claude Code?

The fastest way is the MCPizy CLI: run `mcpizy install vault` and MCPizy will add the server to your `.claude.json` automatically. You can also install it manually by adding an entry under `mcpServers` in `.claude.json` with the command `pip install mcp-server-vault` and restarting Claude Code.

Is HashiCorp Vault MCP free?

Yes. The HashiCorp Vault MCP server is free and open source (see the GitHub repository linked on this page). You may still need a HashiCorp Vault account or API key to connect the server to the underlying service, but the MCP layer itself has no MCPizy subscription cost.

Does HashiCorp Vault MCP work with Cursor and Windsurf?

Yes. Any MCP-compatible client works — including Claude Code, Claude Desktop, Cursor (via `.cursor/mcp.json`), Windsurf, VS Code with Copilot Chat, and custom agents built on the MCP SDK. The same install command targets all of them; only the config file path differs.
