MCP Ecosystem Dataset

A daily-refreshed, research-friendly snapshot of the Model Context Protocol (MCP) server ecosystem, published by mcptoplist.com. It covers every server tracked across the five major MCP registries — the Official MCP Registry, Glama, Smithery, mcp.so, and PulseMCP — deduplicated to canonical entities, with per-registry membership and daily registry growth series.

—Current version: v2026-09-21 (generated 2026-09-21)
—License: CC BY 4.0 — free to use with attribution to mcptoplist.com
—Refresh cadence: daily (~04:30 UTC, after the overnight registry syncs settle); each day is one commit, so any past day is retrievable from the repo history

What is MCP?

The Model Context Protocol is an open standard that lets AI assistants connect to external tools and data sources. Since its launch in November 2024 an ecosystem of tens of thousands of MCP servers has grown across several competing registries. This dataset measures that ecosystem: which servers exist, where they are listed, and how each registry has grown over time.

Files

`servers.parquet` — 132,897 rows, one per canonical server

Registries list the same server under different names and keys; rows here are canonical entities after cross-registry deduplication (repository-URL and package-identifier resolution, plus rename tracking).

Column	Type	Description
`canonical_server_key`	string	Stable canonical key (`srv_` + hash). Joins across dataset versions.
`name`	string	Server name from the canonical listing.
`repo_url`	string	Canonical source repository URL, when known.
`on_official_mcp_registry`	bool	Ever listed on the Official MCP Registry.
`on_glama`	bool	Ever listed on Glama.
`on_smithery`	bool	Ever listed on Smithery.
`on_mcp_so`	bool	Ever listed on mcp.so.
`on_pulsemcp`	bool	Ever listed on PulseMCP.
`first_seen`	date	Earliest date we observed the server on any registry.
`is_active`	bool	Still listed (not delisted/deleted) at generation time.
`transport_classification`	string	`stdio` / remote transport class, when known.
`setup_classification`	string	`runs_out_of_the_box`, `needs_credentials`, or `hosted_remote_auth`; null when unknown.
`repo_stars_current`	int	GitHub stars, snapshot at generation time.
`mcptoplist_rank`	int	The server's position in the mcptoplist.com ranking (1 = top), exactly as published on the site at generation time; null for servers the site does not rank. The underlying score, its components and weights are not part of the dataset — see <https://mcptoplist.com/methodology>.

`registry_daily.parquet` — 745 rows, one per source × day

Column	Type	Description
`source`	string	One of `official_mcp_registry`, `glama_ai`, `smithery`, `mcp_so`, `pulsemcp`.
`date`	date	Calendar day (UTC); the series ends at the last complete day before generation.
`listed_servers`	int	Cumulative count of distinct servers whose listing on this source began on or before this day.

`manifest.json`

Version label, generation timestamp, row counts, and column lists for the release.
