AI Agent Tools (MCP servers, A2A agents)
Frontier, a protocol directory (mcp registry) beside providers' own declarations, with mediation by gateways. The Kin Score Market layer reads each provider in its market:
who it integrates with, how deep those integrations go, and where the market publishes its own structure.
Methodology.
46providers measured
31 (67.4%)declare their own
3 (6.5%)covered by others only
1 (2.2%)distribution only (sell through, not integrations)
11 (23.9%)undeclared
4declare compatibility (report only, not weighted)
Provisional. Provisional and unweighted: the Market layer is not part of the composite or agent readiness. Leader lists are read within a position, never as one ranking. A provider that declares nothing we can
read is shown as undeclared, with no number: we never infer integrations.
Where this market publishes its structure
- Official MCP Registry /v0/servers (verified reverse-DNS namespace = publisher domain) machine-readable
- a2aregistry.org /api/agents machine-readable
- Catalog mcp/*-mcp.yml and a2a/*-a2a.yml (providers' own surfaces, harvested) machine-readable
- Smithery, Glama, mcp.so, Composio, Zapier MCP, Pipedream catalogs not machine-readable: reported as mediation from the registry only; their own catalogs not swept
- io.github.* registry namespaces (62.6% of servers) not machine-readable: GitHub-login verified, no domain; linked only by a non-shared remote domain
Own = declares at least one integration itself; covered = visible only because an aggregator, standards body, regulator or partner contract names it; distribution-only = listed only on cloud marketplaces it sells through, a channel reported beside, never counted as its own declared integrations; undeclared = nothing we can read, so no number; declares_compatibility = providers with a `compatible` shape vote, report only (kin, 2026-10-13): never counted as own, never in depth or position.
Taxonomy how this market maps onto apis.io
Derived 2026-10-15 from the 46 providers in this market we could resolve in the
catalog. The percentage is the share of those providers carrying each one; it describes the market, not the tag or industry. Tag groups have no page of their own yet, so they are listed unlinked.
share of resolved cohort carrying it; tags >=0.20 & >=3 members (max 12, junk dropped), tag_groups >=0.20 (cooccurrence, non-cross-cutting; max 8), industries >=0.20 (max 6), areas >=0.10 (max 6; areas are keyword-matched and sparse), capabilities L1 >=0.20 (max 8); derive-market-taxonomy.py
Leaders by position (provisional)
Provisional: grouped by position, depth compared within a position only. Distribution (cloud marketplaces) and iPaaS bridges are counted beside
position, never inside it. Unknown-builder listings are left out of position shares and counted here.
