Wrapping a Paid API Behind MCP: Vozora's Design Notes on Risk, Limits and Confirmations
Faye-Vozora · reddit · 2026-10-14
VPS provider Vozora shared design notes from shipping a hosted MCP server: treat MCP as a window (every tool call is an ordinary request to the public API with the user's own key, reusing auth, scopes and rate limits), OAuth mints a plain scoped 90-day API key, tools are risk-classified with fixed confirmation lines for spend/destroy/secret operations, server creation requires the agent to echo the quoted price, and per-key spend caps (£20/hr, £100/day) backstop the real failure mode: retry loops, not malice.
