Why Scavio Wins

  • The OP's hard constraint is 'I don't want to pay for those right now'. Path-1 is the cheapest path that works with reasonable shape.
  • Perplexity's March 2026 MCP support (Pro+) made path-1 viable. Before that, attaching custom remote tools to Perplexity was harder; in 2026 it's a settings-page action.
  • Scavio MCP is the constant — it attaches to all five options as the typed multi-platform search layer. Decision is about agent runtime, not search vendor.
  • Honest tradeoff: Q&A-shaped research with manual paste-back works for solo devs on small refactors. For multi-file repository-wide flow, Claude Code / Codex are more native.
  • Per-month math: $50 total if starting fresh, $30 extra if Pro is already paid. Cheaper than Claude Max at $100/mo by a wide margin for users who don't need 6+ hours/day Opus.
