Direct web purchases stay on the web. Credits are how your agent installs paid skills over MCP — same balance works on promptspace.in too.

How It Works

Your agent gets full marketplace access

Four steps to connect. Free search out of the box — paid skills install with credits.

01

Add the MCP URL

Drop the PromptSpace MCP endpoint into your agent's settings. Works with Claude Code, Cursor, Codex CLI, and any MCP-compatible client.

// .claude/settings.json
{
  "mcpServers": {
    "promptspace": {
      "url": "https://mcp.promptspace.in/mcp"
    }
  }
}
02

Agent searches free

Your agent calls search_skills, get_popular, and list_categories at no cost. Discovery is always free — you only pay when you install.

> ps search "code review"

  ✓ code-reviewer       Free
  ✓ ai-smell-detector   Free
  ✓ pr-description-writer  Free
03

Confirm with credits

Paid skills install with credits. Your agent shows the cost and waits for your confirmation before charging.

Cost: 25 credits
Balance: 115 cr → 90 cr after install
Install? [Y/n]
04

Skill loads instantly

After confirmation the SKILL.md file is dropped into your agent's skills folder. Ready on the next turn — no restart.
