The MCP and Agent Skill ecosystem, in numbers.
A live census of every published MCP server and agent skill in the MCPMarkets catalog. Figures are computed on demand — use Refresh for the latest reading. Methodology and daily snapshots are below.
As of Oct 18, 2026, MCPMarkets tracks 13,815 published MCP servers and agent skills.
The long tail, measured
How GitHub stars are spread across 6,723 MCP servers.
As of Oct 18, 2026, 66.7% of MCP server repositories have fewer than 100 stars; the median is 57.
A very narrow head
The Lorenz curve shows how much of all stars the largest repositories hold.
The biggest repositories
Ranked by GitHub stars. Classification follows our ingestion heuristics.
- 1punkpeye/awesome-mcp-servers ★ 96,534MIT
- 2headroomlabs-ai/headroom ★ 75,611Apache-2.0
- 3sansan0/trendradar ★ 62,975GPL-3.0
- 4zylon-ai/private-gpt ★ 57,594Apache-2.0
- 5chromedevtools/chrome-devtools-mcp ★ 53,748Apache-2.0
The top 1% of MCP server repositories hold 49.3% of all stars (Gini 0.870).
What can you actually reuse?
License mix across both catalogs. “Unclear” is the bucket that makes commercial use a question.
MCP servers
Among MCP server entries, 22.4% have no detectable license, which leaves commercial use ambiguous.
Agent skills
Among agent skill entries, 30.4% have no detectable license, which leaves commercial use ambiguous.
Is it still alive?
Time since the last push to the source repository.
64.6% of MCP server repositories have been pushed to in the last six months.
0% of MCP server repositories have been inactive for more than two years.
How these numbers are produced
- Source: the MCPMarkets catalog, built from GitHub's public API (stars, license, last push, README).
- Snapshot: Oct 18, 2026 (UTC day). Historical dates replay the payload stored at the end of that day.
- Counting: published entries only. Total = MCP servers + agent skills; duplicates across the two catalogs are not merged.
- Freshness: statistics are computed when the page loads and cached for 60 seconds; Refresh recomputes immediately. The catalog itself is refreshed by the crawler and the nightly metrics sync. A JSON snapshot is stored daily.
- License groups: permissive = MIT/Apache/BSD/ISC/CC0/Unlicense; copyleft = GPL/AGPL/LGPL/MPL/EPL; unclear = missing value or GitHub NOASSERTION.
- Stars measure attention, not usage or quality. The server/skill split is heuristic and may misclassify a few list-style repositories.
- Coverage: a snapshot can lag the catalog by a few minutes while the crawler publishes new entries.
