Satya Nadella said last week: “The traditional application layer is collapsing.”
Translation: software agents are replacing manual workflows — and if your product is invisible to agents, it’s about to get skipped.
So I built a simple scoring framework and ran it against five real products.
If you’re building SaaS right now, you should probably run this against your own product before someone like me does.
The Framework (6 dimensions, 10 points max)
1) API Existence & Quality (0–2) Does a public REST/GraphQL API exist? Is it documented? Is there an OpenAPI spec?
2) Programmatic Authentication (0–2) Can software authenticate without a human in the loop? API keys? Service accounts? Or is everything gated behind browser-only OAuth?
3) Structured Data Output (0–2) Does the product return machine-readable JSON? Or is everything trapped in rendered HTML that agents have to scrape?
4) MCP / Agent-Native Interface (0–2) Does it have an MCP server, function-calling SDK, or dedicated agent integration layer?
5) Permissions & Safety (0–1) Can you scope what an agent is allowed to do? Read-only vs read-write? Per-resource controls?
6) Agent Observability (0–1) Can product owners distinguish agent traffic from human traffic? Can you see what agents are doing?
The Results (the blunt version)
- Carrd: 0/10
- Balsamiq: 1/10
- Kit (ConvertKit): 6/10
- Plausible Analytics: 7/10
- Ghost: 7/10
Here’s the score breakdown:
| Tool | Score | API | Auth | Data | MCP | Perms | Observability |
|---|---|---|---|---|---|---|---|
| Carrd | 0/10 | ❌ | ❌ | ❌ | ❌ | ❌ | ❌ |
| Balsamiq | 1/10 | ❌ | ❌ | ⚠️ | ❌ | ❌ | ❌ |
| Kit | 6/10 | ✅ | ✅ | ✅ | ❌ | ❌ | ❌ |
| Plausible | 7/10 | ✅ | ✅ | ✅ | ❌ | ❌ | ✅ |
| Ghost | 7/10 | ✅ | ✅ | ✅ | ❌ | ⚠️ | ✅ |
(⚠️ means “sort of” — technically possible, but not nice.)
The Audits
🔴 Carrd — Score: 0/10
Carrd is the best-value website builder on the internet at $19/year.
From an agent-readiness standpoint: it doesn’t exist.
- API: none.
- Auth: browser-only.
- Structured data: none.
- MCP: none.
- Permissions / observability: N/A.
Why it matters: as “build me a landing page for this campaign” becomes an agent workflow, tools without programmatic interfaces won’t be in the loop.
🟡 Balsamiq — Score: 1/10
Balsamiq is fantastic at being intentionally ugly.
But for agents, it’s basically a dead end:
- API: none (the old myBalsamiq API is gone).
- Auth: browser-only.
- Structured data: kinda — BMPR files are XML, so you can parse them if you can get them.
Why it matters: the “sketch → code” pipeline is collapsing fast. If a tool can’t be driven by an agent, it’s not in the next wave.
🟡 Kit (ConvertKit) — Score: 6/10
Kit’s API is solid. It’s built for automation — just not for agents.
- API: 2/2 (documented REST API).
- Auth: 2/2 (API keys / OAuth).
- Structured data: 2/2 (clean JSON).
- MCP: 0/2.
- Permissions: 0/1 (keys are too broad).
- Observability: 0/1.
Why it matters: you can automate newsletters, tags, segments, etc. But there’s no agent-native interface layer, no scoped “agent tokens”, and no clear visibility on what an agent did when things go wrong.
🟢 Plausible Analytics — Score: 7/10
Plausible is the standout.
Their API-first approach (partly driven by GDPR and open-source) accidentally makes them one of the most agent-ready indie SaaS products around.
- API + auth + JSON: all strong.
- Observability: better than most.
- MCP: still missing.
Why it matters: an agent can query Plausible for anomalies, referrers, top pages, trends — and trigger downstream actions without a human.
🟢 Ghost — Score: 7/10
Ghost is unusually agent-friendly for a publishing platform:
- Content API + Admin API.
- JWT auth for Admin.
- Loads of structured JSON.
But it still misses the “agent-native” layer:
- MCP: none.
- Scoped permissions: possible, but not frictionless.
Why it matters: Ghost is already usable by agents today — and a first-party MCP server would turn it into a proper agent-era platform.
The Pattern
Tools built around data + APIs are positioned for the agent era.
Tools built around visual interaction are not.
That gap is only going to widen.
