Not all MCPs are built the same.
The space is exploding right now, every SaaS company is shipping one.
Here's a checklist to evaluate any MCP before you trust it with your data:
✓ Relational schema — not flat API dumps
✓ Pre-computed metrics — answers ready, not raw numbers requiring math
✓ Time-series awareness — trends and comparisons, not just point-in-time
✓ Full granularity: deep data access, not just top-line summaries
✓ Read/write control: can take actions, not just read, but you control it
✓ Context management: stores your goals, strategy, and history
✓ Full data coverage: every source you need, not cherry-picked
✓ Rate limit management: handled in the data layer, not by you
✓ No-code access — your team can use it, not just developers
✓ Doesn't hit token limits on basic questions
✓ Doesn't require manual approval at every step
✓ Doesn't return zeros on queries it should answer
