There is no official DeepWiki MCP server in the registry.
As of the 2026-08-18 registry snapshot (22,395 indexed servers), no entry is published under a Cognition (DeepWiki)-owned namespace (com.deepwiki, ai.deepwiki, io.github.cognition-ai).
No community server in the registry carries this name either.
The registry verifies namespace ownership, so a registered vendor entry is the one identity an agent can pin. Without one there is no verified DeepWiki namespace, no canonical entry to pin a tool contract against, and no drift history when the tool surface changes. A server using the name may still be useful; it is just not Cognition (DeepWiki) speaking.
How mcpindex evaluates what a server declares versus what it does is covered in the methodology and the trust model.
Publishing to the MCP registry gives your users a verifiable namespace. mcpindex syncs the registry daily; a published entry replaces this page with a normal server page, which you can then claim.
