Overview

Gibber MCP is a tiny Model Context Protocol server that provides cryptographic tools for establishing end-to-end encryption between LLM agents.

To use Gibber MCP, clone the repository from GitHub, install the dependencies, and run the server. You can then connect to the server using the provided API endpoints for secure communication.

Generate SJCL P-256 key pairs - Derive shared secrets for secure communication - Encrypt and decrypt messages using SJCL AES-CCM - Real-time communication via server-sent events (SSE)

Secure communication between AI agents
Encrypted messaging for sensitive data exchange
Integration with applications requiring secure data transmission

Use these steps to connect Tiny Cryptography MCP Server in Cursor, Claude, VS Code, and other MCP-compatible apps. The same JSON appears in the Use with menu above for one-click copy.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "gibber-mcp-anton10xr": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-gibber-mcp-anton10xr"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "gibber-mcp-anton10xr": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-gibber-mcp-anton10xr"
      ]
    }
  }
}

Claude Code

Add this to your project's .mcp.json file. Claude Code will detect it automatically.

.mcp.json (project root)

{
  "mcpServers": {
    "gibber-mcp-anton10xr": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-gibber-mcp-anton10xr"
      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{
  "servers": {
    "gibber-mcp-anton10xr": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-gibber-mcp-anton10xr"
      ]
    }
  }
}

Windsurf

Add this to your Windsurf MCP config file, then restart Windsurf.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "gibber-mcp-anton10xr": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-gibber-mcp-anton10xr"
      ]
    }
  }
}

Cline

Open Cline settings, navigate to MCP Servers, and add this server configuration.

Cline MCP Settings (via UI)

{
  "mcpServers": {
    "gibber-mcp-anton10xr": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-gibber-mcp-anton10xr"
      ]
    }
  }
}
