Official MCP Registry

Lock-in risk: higher = more lock-in (worse). Overall already inverts this dimension.

Source of truth for MCP server metadata and the Depot pick for mcp-discovery since 2026-10-24 (replacing Smithery, whose connection services end 2026-10-31). Not a hosting runtime; see mcp-server-hosting.

Pricing notes

As of 2026-10-24 (https://modelcontextprotocol.io/registry/registry-aggregators; https://github.com/modelcontextprotocol/registry/blob/main/docs/reference/api/official-registry-api.md): 'The MCP Registry provides an unauthenticated read-only REST API that aggregators can use to populate their data stores.' Base URL https://registry.modelcontextprotocol.io, GET /v0.1/servers ('List all servers.'), cursor pagination; 'Aggregators are expected to scrape data on a regular but infrequent basis (e.g., once per hour)'. Search: 'Case-insensitive substring search on server names' ('This is intentionally simple. For more advanced searching and filtering, use a subregistry.'). 'The MCP Registry is currently in preview. Breaking changes or data resets may occur before general availability.' 'The MCP Registry does not provide uptime or data durability guarantees'. Publishing: 'Publishing requires namespace-based authentication'. Neither page publishes a price or plan; no price is stated here. Not a hosting runtime: 'Aggregators are downstream consumers of the MCP Registry that provide additional value.' 'For example, a server marketplace that provides user ratings and security scanning.'
