This release covers the `@yugabytedb/meko-mcp` installer, the Meko MCP server, and the Claude Code, Claude Desktop, Cursor, and Codex agent skills — the pieces you get from the [Automated install](../../../quick-start/#connect-your-ai-client) flow and the [MCP server reference](../../../reference/mcp-server/).

### New Features

#### MCP Server

- **Implicit memory extraction** — the marquee change in this release. Posting a substantive conversation turn (via automatic capture or an explicit `conversation_add_message`) now gives Meko what it needs to build durable memory on its own, asynchronously. See [Work with memory](../../../guides/working-with-memory/#automatically-from-saved-conversations).
- **Artifact storage** — `artifact_put` and `artifact_get` add MCP-native storage and retrieval for files an agent generates (reports, CSVs, code output) for later or cross-agent access.
- **Datapack-aware automatic capture** — automatic capture (Claude Code hooks, Claude Desktop skill) now writes to your pinned datapack instead of always falling back to the account default. See [Automatic capture and datapack pinning](../../../architecture/core-concepts/datapacks/#automatic-capture-and-datapack-pinning).

#### Integrations

- **Claude Desktop datapack selector** — pick, switch, or clear which datapack automatic capture writes to, without leaving the chat.

### Improvements

#### Integrations

- **More reliable Claude Desktop capture** — the Desktop skill now presents Meko as your memory/knowledge/observability system of record, which meaningfully improves proactive capture on cautious models when paired with the documented Instructions for Claude snippet. See [Troubleshooting](../../../troubleshooting/#common-problems-installing-and-connecting).
- **Codex and Cursor install stability** — hooks and skills installed by the npm installer now copy into a stable, home-directory-owned location instead of pointing back into an ephemeral npx cache, so they survive npx cache eviction.

### Bug Fixes

#### Integrations

- **Requests blocked by Cloud's WAF** — installer-generated configs for every supported client (Claude Code, Cursor, Claude Desktop, the Desktop Extension, Codex) now send an explicit `User-Agent` header, fixing intermittent `403` responses.
- **Claude Desktop Extension bearer token truncation** — the `.mcpb` launcher no longer lets shell parsing split the `Authorization: Bearer <token>` header, which had been silently dropping the token.

### Changes

#### MCP Server

- **Breaking: memory capture doctrine** — agents should post substantive turns with `conversation_add_message` instead of calling `memory_add` for every stated fact; extraction now happens automatically from posted turns. Explicit `memory_add` is still the right tool for direct "remember this" requests, facts that only exist in an assistant's or tool's output, and corrections that must supersede an already-extracted fact.
- **`flush_pending_memory_candidates` deprecated** — kept for one release for backward compatibility; use automatic capture or `conversation_add_message` instead. See the [MCP server reference](../../../reference/mcp-server/#memory-tools).

### Known limitations

- **`contextual_prominence_search` is disabled on Meko Cloud** — it's listed in the tool surface for forward reference, but an authenticated call currently returns `feature_disabled`. Use `conversation_search`, `memory_search`, and `knowledgebase_search` individually instead.
- **Claude Desktop automatic capture is model-dependent** — Sonnet- and Opus-class models need the Instructions for Claude snippet to capture proactively; hookless Desktop capture remains best-effort even with it.
- **Automatic extraction is best-effort** — it can occasionally miss an individual fact within a saved turn. Use explicit `memory_add` for anything that must not be lost.
- **A datapack pin change doesn't move your current conversation** — a conversation can't switch datapacks after it's created, so a pin change takes effect starting with your next new session.
