Compatible with every major AI agent and IDE
What is the HashiCorp Vault MCP Server?
Connect your HashiCorp Vault instance to any AI agent to automate secrets management and security operations through natural language.
What you can do
- Secrets Management — Read, write, and list KV secrets directly from your secure mounts using the KV engine.
- Dynamic Credentials — Generate on-demand credentials for Databases, AWS, and PKI certificates without manual intervention.
- Token Operations — Create, lookup, and renew tokens to manage session lifecycles and access control.
- Transit Encryption — Encrypt and decrypt data using Vault's transit engine to protect sensitive information without exposing keys.
- System Administration — Check cluster health, manage mounts, and configure auth methods or ACL policies directly.
How it works
- Subscribe to this server
- Provide your Vault Address and Token
- Start managing your infrastructure security from Claude, Cursor, or any MCP-compatible client
Who is this for?
- DevOps Engineers — automate secret rotation and infrastructure provisioning workflows.
- Security Teams — audit token accessors and manage ACL policies through conversation.
- Developers — fetch development secrets and generate local database credentials without leaving the IDE.

Frequently asked questions
Can I check the remaining TTL and policies of my current session token?
Yes. Use the lookup_self_token tool. It returns the creation time, TTL, associated policies, and metadata for the token currently in use.
How do I retrieve a specific secret from a KV version 2 engine?
Use the read_kv_secret tool by providing the path to the secret. The agent will fetch the data and present the key-value pairs securely.
Is it possible to generate temporary database credentials through the agent?
Yes. If the database engine is configured, use generate_database_creds with the specific role name to receive a temporary username and password.
How does Claude Desktop discover MCP tools?
When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.
What happens if the MCP server is temporarily unavailable?
Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.
Can I connect multiple MCP servers simultaneously?
Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.
Is there a limit on the number of tools per server?
Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.
Does Claude Desktop support Streamable HTTP transport?
Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
