Start with one painful workflow, record it as an MCP, iterate.
Don’t blindly trust outputs; keep humans in loop early.
Measure hours saved to justify rollout.
Talk shifts to model routing.
Each step returns uncertainty; high‑risk tasks use bigger models.

Key‑points analysis

Practical upside – If MCPs mature, Cursor could kill the swivel‑chair work of juggling finance, QA, and marketing dashboards, especially for sub‑50‑person teams.
Integration depth – Replacing an “entire stack” hinges on MCP coverage; heavy ERP or complex CRM workflows will still need bespoke code for now.
Governance gap – No per‑field RBAC or SOC‑2 yet: larger enterprises can’t adopt until audit trails and permission models harden.
Reliability risk – Even with 99 % success, a single hallucinated journal entry could wreck books; expect human‑in‑the‑loop to persist for regulated flows.
Economics – Marketplace fee split is attractive for devs; but double‑billing on vendor APIs may erode savings at scale—watch your blended cost of automation.
Competitive landscape – VS Code + Copilot or n8n + Devin could undercut Cursor if they ship comparable agent routing; Cursor’s open MCP network must grow fast.
Strategic play – Early adopters should publish niche MCPs (e.g., industry‑specific ERPs) to lock in marketplace share before incumbents arrive.
Change management – Biggest blocker is not tech but convincing finance and marketing leads to work inside a code editor; pair training with quick‑win workflows.
Forward outlook – IDE‑centric agents feel inevitable, but consolidation won’t happen until security, reliability, and cost transparency reach SaaS parity.
Bottom line – Pilot Cursor for one high‑ROI workflow; measure hours saved versus credits burned, and expand only if governance and cost metrics clear your bar.
