Independent testing will determine whether Cogni’s released MCP memory system provides useful persistent LLM memory and competitive retrieval quality without placing an LLM in the retrieval path.

What is this?
Cogni has announced an MCP memory server intended to give models persistent memory, with its Show HN title claiming that no LLM is placed in the retrieval path. The supplied material does not provide independent tests of its retrieval quality or practical usefulness. Several search results concern the similarly named Cognee rather than clearly establishing details about Cogni, so claims about retrieval modes, storage backends, and integrations cannot be confidently attributed to this release.
Why it matters to Scott
Scott already holds the core position in “Long-Running Agents,” “Search What Churns,” and “Retail MCP Is the Doorway Not the Memory”: persistent state should live outside the model, with deterministic or conventional retrieval where appropriate and MCP serving as an interface. Cogni is currently another untested implementation of that pattern; without independent retrieval results or architectural detail, it does not yet change what Scott would build or argue.

No independent testing, implementation evidence, or adoption has appeared; Cogni remains an unvalidated example of an already-known memory pattern rather than an active developing signal.
