MCP Server
A Model Context Protocol server makes the API directly callable by agents over a uniform tool surface — the most direct expression of agent-first design.PROVENANCE-GRADED IN 0.6. Across four national banking markets exactly one institution ran a genuinely hosted MCP; in UK insurance the data credited 14.3% of the cohort and the real number was zero. Catalog-wide, 1,882 of 3,046 MCP artifacts are derived candidates with no URL. Twelve points is the third-largest award in this model and it was being paid, more often than not, for a server nobody can connect to.
How it is scored
One signal, read from what the provider publishes, worth 12 points of the 139 in the agent-readiness score.
| Signal the scorer reads | Points |
|---|---|
deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship | 12 |
Grades and what each earns
This dimension is graded rather than pass/fail: how the signal was evidenced decides what fraction of the points it earns.

mcp artifact class. API Evangelist derives artifacts on
providers' behalf and marks each one as it writes it; a derived artifact earns a quarter of the
award rather than all of it, because it is a real, fetchable artifact but it is not evidence
about the provider.
