Connect Claude to Glacier

Glacier's MCP server lets Claude read and write your workspace natively — create cards, move them across the board, draft docs, and pull metrics, all without leaving your conversation. Connection takes under two minutes.

Before you start

  • A Glacier account (any plan)
  • One of: Claude.ai (Pro or Team), Claude Desktop, or Claude Code
  • For Claude Desktop: a Glacier API key — get one from Account Settings → MCP API Key → Generate key

Connect from Claude.ai

Claude.ai supports MCP Connectors with one-click OAuth. No API key needed.

  1. Open claude.ai and go to Settings → Connectors (or Integrations, depending on your plan).
  2. Click Add connector.
  3. Paste the Glacier MCP URL: 
    https://getglacier.ai/api/mcp
  4. Glacier's sign-in page will open. Sign in with your Glacier account email (this doesn't need to match your Claude.ai email).
  5. Click Authorize.

Claude now has access to your Glacier workspace from any conversation.

Already connected but tools aren't showing? Remove the Glacier connector and re-add it — this triggers a fresh OAuth sign-in.

Connect from Claude Desktop

Claude Desktop uses a static API key rather than OAuth.

  1. In Glacier, go to Account Settings → MCP API Key and click Generate key. Copy it — it's shown once and starts with glc_sk_.
  2. Open your Claude Desktop config file:
    • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
    • Windows: %APPDATA%\Claude\claude_desktop_config.json
  3. Add Glacier under mcpServers:
{
  "mcpServers": {
    "glacier": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/client-http"],
      "env": {
        "MCP_SERVER_URL": "https://getglacier.ai/api/mcp",
        "MCP_AUTH_TOKEN": "glc_sk_your-key-here"
      }
    }
  }
}
  1. Quit and reopen Claude Desktop. The Glacier tools appear in the tool panel.

Tip: Copy the pre-filled snippet from Project Settings → MCP & developer → Quick setup → Claude Desktop inside the Glacier app.

Connect from Claude Code

Claude Code (the CLI) supports OAuth — no API key required.

claude mcp add --transport http glacier https://getglacier.ai/api/mcp

On first connection, Claude Code opens a browser window for a one-time sign-in. After that, tokens refresh automatically and persist across sessions.

Prefer a static token? Pass your API key as a header instead:

claude mcp add --transport http glacier https://getglacier.ai/api/mcp \
  --header "Authorization: Bearer glc_sk_your-key-here"

Or add it manually to your project's .mcp.json:

{
  "mcpServers": {
    "glacier": {
      "type": "http",
      "url": "https://getglacier.ai/api/mcp"
    }
  }
}

Tip: You can also copy either snippet pre-filled from Project Settings → MCP & developer → Quick setup inside Glacier.

Multi-workspace accounts

If your Glacier account belongs to more than one workspace, Claude sees all of them after sign-in. Use list_workspaces to discover the workspace IDs, then pass workspace_id to board and card tools to target the right one.

"List my Glacier workspaces and tell me what projects are in each."

What Claude can do

Once connected, Claude has tools for the full Glacier workflow.

Board

  • List columns and cards, check WIP limits
  • Create cards from a brief — one at a time or in batch
  • Move cards between columns, update fields, set priority
  • Read card descriptions, labels, assignees, and linked GitHub issues

Docs

  • List, read, create, and update workspace docs
  • Link a doc to a card, or create a doc from a meeting summary

Metrics

  • Pull throughput and cycle time for any project
  • Generate weekly status reports grounded in real data

Team & organisation

  • List workspace members and roles
  • List and create labels

Troubleshooting

Tools don't appear in Claude Code. Check that your .mcp.json or ~/.claude.json has the correct URL: https://getglacier.ai/api/mcp. If you're using OAuth, make sure you completed the browser sign-in when Claude Code first connected. Re-add the server entry and restart Claude Code to trigger a fresh sign-in.

Tools don't appear in Claude.ai. Remove the Glacier connector from Claude.ai settings and re-add it — this reruns the OAuth flow.

401 Unauthorized. Your API key may have been rotated, or your OAuth session may have expired. For OAuth, re-add the connector or reconnect from Claude Code. For API keys, generate a new key in Account Settings and update your config.

Wrong email warning during OAuth. Use the email tied to your Glacier account on the Glacier sign-in screen — it doesn't need to match the email on your AI tool. If you accidentally signed in with the wrong email, disconnect and reconnect to restart the OAuth flow.

Claude can't find a project. Make sure you're passing the correct workspace_id to workspace-level tools. Use list_workspaces to confirm the ID.
