Are most MCP servers local or remote?

Of the 18,032 servers whose transport could be determined, 65% run locally over stdio and 35% are remote HTTP endpoints. Local servers are started by the client as a subprocess; remote servers are hosted and reached over Streamable HTTP.

Are MCP servers mostly JavaScript or Python?

Among stdio servers with a known runner, 72% launch with npx (Node.js packages) and 26% with uvx (Python packages). The runner reflects how the server is distributed, which is a close proxy for its implementation language.

Do MCP servers need API keys?

Where authentication could be determined (3,345 servers), 53% require credentials such as an API key or OAuth, and the rest need none. Servers that wrap third-party SaaS APIs almost always need a key; local utilities usually do not.

How healthy is the MCP ecosystem?

97% of indexed servers passed their most recent automated health check (repository and endpoint reachability, rechecked continuously). 473 of 12,783 scanned install packages have at least one critical or high advisory recorded against some version.

Local vs remote servers

65% of servers with a known transport run locally; 35% are hosted remote endpoints.

Local (stdio)44%11,798
Remote (HTTP)23%6,234
Not determined33%8,895

Install transport across all active servers, as extracted from each server's documentation. Local servers run as a client subprocess; remote servers are reached over HTTP.

Methodology and citing this data

Figures cover listings with active status in AllMCPs, which ingests public MCP servers from the official MCP Registry, community server lists and direct submissions, merges duplicates, and removes archived or deleted repositories. Transport, runner, auth, pricing and license are extracted from each server's documentation and verified where possible; values that could not be determined are excluded from the shares that depend on them. Numbers refresh every few hours; last computed 2026-10-10 23:22 UTC.

You are welcome to cite these figures with a link to this page (CC BY 4.0). Programmatic access is available through the AllMCPs API.
