Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@tankpkg/mcp-server) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Installation

Claude Code

Add to .claude/settings.json or your project's .mcp.json:

{
  "mcpServers": {
    "tank": {
      "command": "npx",
      "args": ["-y", "@tankpkg/mcp-server"]
    }
  }
}

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "tank": {
      "command": "npx",
      "args": ["-y", "@tankpkg/mcp-server"]
    }
  }
}

VS Code (Copilot)

Add to .vscode/mcp.json:

{
  "servers": {
    "tank": {
      "command": "npx",
      "args": ["-y", "@tankpkg/mcp-server"]
    }
  }
}

Authentication

The MCP server shares authentication with the Tank CLI. If you've already run tank login, you're authenticated!

Alternatively, set the TANK_TOKEN environment variable:

{
  "mcpServers": {
    "tank": {
      "command": "npx",
      "args": ["-y", "@tankpkg/mcp-server"],
      "env": {
        "TANK_TOKEN": "tank_your_token_here"
      }
    }
  }
}

Usage Examples

Once configured, talk to your AI agent naturally:

"Initialize a new skill in this directory"
"Scan my skill for security issues"
"Publish my skill to Tank"
"Install @acme/code-review"
"Update all my skills"
"Search Tank for testing skills"
"Show permissions for my installed skills"
"Run tank doctor to check my setup"
"Audit @acme/code-review for security issues"
"Link this skill to my Claude workspace"
