Common approaches to pricing MCP server tools:
| Strategy | Description | Best For |
|---|---|---|
| Per-call flat rate | Fixed price per tool invocation (e.g., $0.01/call) | Simple tools with consistent compute cost |
| Per-token metered | Price based on input/output token count | LLM-wrapper tools, text processing |
| Tiered pricing | Different price tiers based on volume | High-volume enterprise users |
| Freemium | Free credits on signup, paid after threshold | Growing user base, low-friction onboarding |
| Dynamic pricing | Price adjusts based on complexity or demand | Variable-cost tools (API aggregators, search) |
