Agent-readiness dimension

MCP Tool Quality

6 of 153 agent-readiness points 3.9% of the agent scoregraded — partial credit mcp_tool_quality

0.26.0 (roadmap#994, promoted from the 0.25 observed signal). Whether an agent can use a server's tools safely and cheaply: annotated hazards, described parameters, and a tool list that fits in a context window. Not applicable without a live capture, or for a platform-authored server whose tool shape is not the provider's design (mcp_server already discounts those).

314at full credit
249at partial credit
36,145not applicable
36,145 providers are scored na on this dimension, not zero. A read-only surface carries no write hazard to mitigate, so since rubric 0.12 this dimension leaves their denominator entirely rather than handing them a zero for something they cannot have. Every number on this page is over the 565 providers it does apply to.

How it is scored

One signal, read from what the provider publishes, worth 6 points of the 153 in the agent-readiness score.

Signal the scorer readsPoints
graded from the `tool_quality` block of the provider's mcp/ manifest (a live tools/list capture, mcp_tool_quality.py); the 0-1 credit of the four sub-checks, rounded to the nearest quarter; na with no capture or a platform-authored server6

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.

The other 21 dimensions

Move this number. Every provider in the catalog is profiled into a public record at artifacts.apis.io/<provider>/, and each check above names the exact artifact it reads. Publish the artifact, open an issue on github.com/api-evangelist/<provider> pointing at it, and the next scoring run picks it up — no gatekeeping and no fee. The full rubric is at apis.io/rating/, and the Influence plan is the fast lane if you would rather work your own listing through the API — remediation, projections and re-check requests.

Scored on rubric v0.26.0 across 36,710 providers · lists rebuilt 2026-11-01 · capped at the top 500 per page.
