Connect to the Aperture MCP server and run a safe first check.

1. Add it as an MCP server named "aperture" at https://calm-steel-d31rh.run.mcp-use.com/mcp. Use your client's own MCP setup. In Claude Code: claude mcp add --transport http "aperture" 'https://calm-steel-d31rh.run.mcp-use.com/mcp'
2. If it asks you to sign in, use the sign-in flow it provides. Never ask me to paste a password or key into this chat.
3. List the tools it exposes. For each one, tell me what it does and whether it only reads or can change data.
4. Make one read-only call and show me the result. Change nothing.

Stop and ask me before anything that writes, deletes, or sends.
