v0.4.2 — descriptions people actually search for
Metadata only. No runtime code changed — packages/*/src is byte-identical to 0.4.1.
@zensation/mcp and @zensation/ai-sdk move 0.1.1 → 0.1.2; the other four are untouched.
Changed — the npm descriptions of the two integration packages
npm's search ranks on the words in a package's description, and it weighs that far above
download counts. For the query vercel ai sdk memory, @turbomem/vercel-ai (142 downloads a
month) ranks first and ai (90,669,436 downloads a month) second. Of the fifteen top results
for mcp memory, three carry no keywords at all; what all fifteen have in common is those two
words standing next to each other in a name or a description.
Neither of these packages had that. @zensation/mcp said "gives any MCP client a 7-layer
memory" and @zensation/ai-sdk said "recall relevant memories before a model call" — both
accurate, and neither in the top 250 for any phrase someone looking for this would actually
type, while @mem0/vercel-ai-provider, the direct counterpart to @zensation/ai-sdk, sits at
39. The new descriptions put the phrases together and claim nothing new:
@zensation/mcp— "MCP memory server for ZenBrain: agent memory for any Model Context Protocol client — store, recall, consolidate, health. Local SQLite file, no account."@zensation/ai-sdk— "Vercel AI SDK memory middleware: agent memory that recalls before a model call and stores the turn after it. Zero runtime dependencies."
Whether this moves anything is an open question, and it is measured the same way it was found:
the same queries, re-run, with 7-layer memory → @zensation/core at rank 1 as the control
that the instrument still works.
Fixed — documentation that had drifted from what is published
- The old
@zensation/mcpdescription named a toolinspect. There is no such tool. The four
arezenbrain_store,zenbrain_recall,zenbrain_consolidateandzenbrain_health. - The package table in the README listed
@zensation/mcpand@zensation/ai-sdkas
:construction: Unreleased. Both have been on npm with provenance attestations since
2026-08-28. - Both package READMEs opened with "Status: 0.1.0, early release" while
0.1.1was the
published version. The version number is out of the sentence — the status was the point, and
a pinned number there only ages. @zensation/ai-sdkdid not appear in this changelog at all. It is Vercel AI SDK middleware:
it recalls before the model call and stores the turn after it, carries zero runtime
dependencies, and its twelve tests assert ondoGenerateCalls[0].prompt— what reached the
model — rather than on what the middleware returned.
