Clavis MCP Server: Secure Credential Management for Claude Desktop
Ad

Clavis is an MCP server built to solve credential management issues in Claude Desktop. Instead of storing API keys directly in Claude Desktop's config file or dealing with OAuth tokens expiring mid-conversation, Clavis acts as a credential manager between Claude Desktop and your APIs.

How It Works

You store credentials once in Clavis (encrypted with AES-256), and MCP servers pull them as needed with automatic token refresh. The developer built the entire MCP server implementation using Claude Code, including the FastAPI backend and credential encryption logic.

Key Features

  • Auto token refresh — OAuth tokens refresh before expiry
  • Rate limiting — distributed limits across multiple agent instances
  • Audit logging — complete trail of credential access
  • Dry-run mode — check status without consuming API rate limits
  • Encrypted storage — AES-256 encryption at rest

Supported Services

OpenAI, Anthropic, Stripe, GitHub, Brave Search, Kalshi, Coinbase, plus any custom OAuth2 provider.

Installation

Install via npm:

npm install -g @clavisagent/mcp-server

Add to Claude Desktop config:

{
  "mcpServers": {
    "clavis": {
      "command": "clavis-mcp",
      "env": {
        "CLAVIS_API_KEY": "your-api-key-here"
      }
    }
  }
}

The tool is free to try at clavisagent.com/register with a free tier available. Full documentation is at clavisagent.com/docs/mcp.html, and it has been submitted to the official MCP server directory.

Reddit discussion: Identity.md files insufficient for AI employee personality stability without proper model architecture

A Reddit discussion argues that adjusting identity.md files to prevent personality bleed in AI employee teams is ineffective if the underlying model architecture only simulates role separation. The post recommends using Minimax M2.7 backend, which baked boundary awareness into base training through 100+ self-evolution cycles.
