Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

claude mcp add --transport http toolbelt 'https://mcp.toolbelt.ai/mcp' --header 'Authorization: <Bearer token from https://app.toolbelt.ai/api/onboard (free anonymous account)>'

@toolbeltai/skills

The official skill for Toolbelt. Installs one /toolbelt skill that any MCP-capable agent can use to connect to a Toolbelt namespace and hand off to Toolbelt's MCP tools.

Install

npx @toolbeltai/skills install

Copies toolbelt/SKILL.md into ~/.claude/skills/toolbelt/ (flat layout per the AgentSkills spec). Restart your client; the skill appears as /toolbelt.

No Toolbelt account required — the skill provisions one on first use.

What the skill does

When an agent runs /toolbelt for the first time, it:

  1. Checks for an existing Toolbelt MCP connection.
  2. If none, calls the public /api/onboard endpoint to provision a free anonymous account.
  3. Writes the MCP connection into the agent's client config.
  4. Hands off to Toolbelt's MCP tools for the actual work.

Full playbook in toolbelt/SKILL.md.

Works with

Claude Code · Claude Desktop · OpenClaw · Cursor · Gemini CLI · Codex CLI · Windsurf · any MCP client.
