One key. Drop it into Claude Code, Cursor, or Codex and your agent can search 539k+ skills, MCP servers and agents — and install the right ones into its own directory, by itself.
Create a free skillcity API key — your agent’s passport to the catalog.
Paste one MCP block into Claude Code, Cursor, or Codex (or set it in your CLI env).
Your agent searches the catalog and installs the right skills into its own directory, on demand.
Sign in to generate your free agent key. It takes one click and the free tier covers 10 agent calls a day.
Snippets use a placeholder key — generate yours above and it auto-fills here.
One command
claude mcp add skillcity -e SKILLCITY_API_KEY=sc_live_xxxxxxxxxxxxxxxxxxxx -- npx -y skillcity-mcp
or add to .mcp.json
{
"mcpServers": {
"skillcity": {
"command": "npx",
"args": ["-y", "skillcity-mcp"],
"env": { "SKILLCITY_API_KEY": "sc_live_xxxxxxxxxxxxxxxxxxxx" }
}
}
}Restart your agent after adding the config. Then ask it to “find and install a skill for <task>” — it’ll search the catalog and install on its own.
search_skills()
Semantic search across the whole catalog — returns the best skills, MCPs and agents for a task.
get_skill()
Pulls a skill’s SKILL.md so the agent can read exactly what it does before installing.
install_skill()
Downloads and installs a skill straight into the agent’s skills directory.
