Accounting vs HR & Payroll: the back office, compared
Accounting and finance-ops platforms outscore HR and payroll by 4.2 points and ship first-party MCP at nearly twice the rate.
Accounting & Finance Operations
Human Resources & Payroll
Each sun is drawn from the cohort's averages: six facet rings, the mean Kin Score and mean agent readiness.
Both are back-office software, and both are increasingly the system an agent needs to read and write. The 920 scored accounting and finance-operations providers average 27.4, against 23.2 for 884 HR and payroll providers. Accounting holds 16 exemplars to HR’s 9, and the medians are 24.2 against 17.9.
Accounting leads on every facet, most clearly on developer ergonomics (26.9 against 20.8), contract quality (22.1 against 17.4) and operational transparency (16.8 against 12.2). On agents, 20% of accounting providers publish a first-party MCP server, against 12% in HR and payroll. Agent readiness is 16.2 against 12.2.
HR and payroll has the single highest score in this pair, 95.3, so the market’s best is excellent and its middle is thin. The delta is depth-confounded: three more artifact directories on the median accounting member. See Gusto vs Rippling for two HR platforms head to head.
The distributions
| Accounting & Finance Operations | Human Resources & Payroll | Delta | |
|---|---|---|---|
| Kin Score, mean | 27.4 | 23.2 | +4.2 |
| Kin Score, median | 24.2 | 17.9 | +6.3 |
| Kin Score, highest | 84.5 | 95.3 | |
| Kin Score, std dev | 17.8 | 16.4 | |
| Agent readiness, mean | 16.2 | 12.2 | +4 |
| Agent readiness, highest | 66.2 | 69.1 |
Delta is Accounting & Finance Operations minus Human Resources & Payroll, as the tool returns it.

What they publish
Share of each cohort's providers publishing each artifact. mcp_pct counts any mcp/ artifact including ones API Evangelist derived from the provider OpenAPI; mcp_first_party_pct counts only servers the provider publishes. Prefer the latter.
| Artifact | Accounting & Finance Operations | Human Resources & Payroll | Delta |
|---|---|---|---|
| First-party MCP server | 20% | 12% | +8 |
| Any MCP artifact (incl. derived) | 21% | 13% | +8 |
| OAuth scopes | 17% | 14% | +3 |
| Spectral rules | 16% | 13% | +3 |
| Arazzo workflows | 2% | 2% | 0 |
| Agent skills | 0% | 0% | 0 |
| Security artifact | 99% | 99% | 0 |
How well we know each cohort
The coverage behind the averages. A cohort with a higher catalog gap and fewer artifact directories has been enriched less, so part of any difference is our coverage rather than the market.
| Accounting & Finance Operations | Human Resources & Payroll | |
|---|---|---|
| Declared members | 948 | 928 |
| Scored (in the averages) | 920 (97%) | 884 (95%) |
| Thinly covered | 827 | 802 |
| Median artifact directories | 11 | 8 |
| Mean catalog gap (points we could add) | 76.1 | 78.5 |
