Each data source has a complexity weight (1–4) reflecting integration cost, schema design effort, and failure-mode coverage. Auth model adds 0–5 points. Tool count adds 1 point per 5 tools. Write operations add 2 points (idempotency, rollback, validation). Governance adds 4 points (audit trail, RBAC, rate-limiting, SLA-backed observability).
Tiers are tuned to current 2026 market rates for senior MCP development. Real engagements price against a written scope: tool schema, auth architecture, eval harness, and observability budget.
