## Which one, for what

### Agent Platform Memory Bank (B)

Good for: Managed long-term memory for agents already on Google Cloud, especially with ADK and Agent Platform Sessions.

Ahead on:
- Reliability, 68 against 27
- Agent ergonomics, 75 against 57
- Security & auth, 72 against 65
- Transparency & trust, 81 against 50

Also in its favour:
- No incidents deducted, where Hindsight loses 6 points for them

Watch for: Needs a Google Cloud project with billing, set up by a person in the console

### Hindsight (D)

Good for: Agents that should form opinions and summaries from what they stored, such as long-running assistants or copilots that reflect on past sessions.

Ahead on:
- Payments & pricing, 30 against 20
- Maintenance & community, 80 against 62

Also in its favour:
- Open source

Watch for: Retain at $10 per million tokens is the priciest ingestion in this category


## Why the edge

### Reliability: Agent Platform Memory Bank +41

- Agent Platform Memory Bank (68): Hosted lines. Google Cloud status dashboard with per-product history (20). Its incident feed, read on 6 November 2026, holds four incidents since 8 August (20 August, 27 products; 1 September, us-central1-b; 8 October, Cloud Storage; 20 October, europe-west2, 38 products), and none names Agent Platform, Vertex or Memory Bank (30). No Memory Bank quotas or rate limits were found; the platform quotas path guessed returned 404 (0, unchecked). Generation is a long-running operation with wait and cancel methods, and Google's retry guidance wasn't re-read for this API (8 of 15). No SLA for Memory Bank was found in the pages read (0, unchecked). Memory profiles, IngestEvents and multi-regional endpoints are GA (10). Total 68.
- Hindsight (27): Vectorize's footer now links a status page at status.hindsight.vectorize.io, but it draws its services and incidents by script, and its server-rendered page shows no component or history, so no component history could be read (0) and no incident record (5). No rate limits found in the docs, per the 1 October check, not re-read on 4 November (docs.hindsight.vectorize.io answers robots.txt with its app page) (0). The Hindsight Cloud 0.10.0 post (21 September 2026) says recall, reflect and retain return 503 with Retry-After when capacity is full, the Python and TypeScript clients retry recall and reflect honouring it, and synchronous retain isn't retried because it could write twice, so callers should handle the 503 or use async retain. Overload handling with safe-retry guidance and no idempotency keys (12). The pricing page lists a 99.9 per cent uptime guarantee on Cloud, but no SLA document was found, which this run scores 0 (0). Hindsight Cloud is sold as a generally available service (10).

### Transparency & trust: Agent Platform Memory Bank +31

- Agent Platform Memory Bank (81): Closed service under the Google Cloud terms (15). Data residency at rest, CMEK and the Cloud Data Processing Addendum apply; no Memory Bank retention period or time-to-live was read (20 of 30). The rename was announced in the release notes with old and new names listed, and Google's deprecation policy covers GA services (14 of 20). Google Cloud's subprocessor list and regional endpoints are published (16 of 20). Total 65.
- Hindsight (50): The server is MIT and runs the same engine, while Cloud adds closed Enterprise extras such as the advanced detectors in `Memory Defense` (20 of 30). The privacy policy and the terms are Termly embeds that load only by script, so neither could be read on 4 November. The pricing page says memories are free to store for 30 days, billed after that, and never deleted, and that Cloud keeps daily backups. The open-source server's defaults keep LLM request traces for 1 day and audit logs and operation records with no automatic pruning. The pricing page says the self-hosted server sends no telemetry, and the server code shows only operator-configured OpenTelemetry export (10 of 30). No deprecation policy found. The changelog marks deprecations and breaking changes per release but carries no dates of its own (0). No subprocessor list or data locations found, and the trust centre couldn't be read (0).

### Agent ergonomics: Agent Platform Memory Bank +18

- Agent Platform Memory Bank (75): Retrieval takes a scope and similarity search with a result limit (20 of 25). List methods page with page tokens and filters (16 of 20). Google's standard error model with status codes (15 of 20). Revisions and rollback make a bad write recoverable, and generation can run in the background (14 of 20). Python SDK and ADK integration, with REST for other languages (10 of 15). Total 75.
- Hindsight (57): 27 MCP tools on a bank-scoped URL and 30 at the root (15), with no documented way to load a subset or a read-only set. List and recall calls exist with bank scoping, and we didn't confirm page-size or token-budget limits (12 of 20). 402 tells an agent it's out of credit and 403 that the key can't reach the bank (12 of 20). No idempotency keys and no readOnlyHint or destructiveHint on the MCP tools, though retain can run asynchronously (3 of 20). Clients for Python, TypeScript and Go, and one URL per bank keeps calls simple (15). MCP and key docs per the 1 October check, not re-read on 4 November (docs.hindsight.vectorize.io answers robots.txt with its app page).

### Maintenance & community: Hindsight +18

- Agent Platform Memory Bank (62): The newest Memory Bank release notes are of 20 August 2026 (IngestEvents GA, metadata, Gemini Embedding 2), 78 days before the check, and billing started on 1 September (20). Three Memory Bank entries in the 90 days, all on 20 August (10 of 20). Public release notes and Cloud Customer Care (12 of 15). `google-cloud-agentplatform` 2.7.0 on 28 October 2026, twelve releases in 90 days per its PyPI release feed, plus ADK (15). SDK test status not checked (5 of 10). Total 62.
- Hindsight (80): Tag v1.2.0 on 3 November 2026, the day before the check (30). Ten core releases since 6 August, v0.9.0 (7 August), v0.9.1 (14 August), v0.9.2 (25 August), v0.10.0 to v0.10.3 (14 September to 8 October), v1.0.0 (13 October), v1.1.0 (21 October) and v1.2.0 (20). We didn't check issue reply times on GitHub (10 of 25). Current clients for Python, TypeScript and Go, though the hosted MCP isn't in the official registry (15). Python 3.11 or later, and a test workflow in the repository whose result we couldn't read (5 of 10).

### Payments & pricing: Hindsight +10

- Agent Platform Memory Bank (20): No x402, MPP or L402 (0). Storage, read and write prices are published without a login (20). No Memory Bank free tier found (0). A person creates the project, enables billing and sets up IAM in the console (0). Total 20.
- Hindsight (30): No x402, MPP or L402. Calls on an empty balance return 402 with no payment payload (0). Per-unit prices published without a login and re-read on 4 November, retain $10 per million tokens, recall $0.75 per million, reflect $0.05 a call, Iris Extract $7.50 per million, mental model retrieval $0.25 per million and refresh $0.05 a call, storage $0.25 per million tokens a month after the first 30 days (20). The pricing page says new accounts start with $5 of free credit; whether a card is needed isn't stated (10 of 20). A person signs up in the browser to get a key (0).

### Security & auth: Agent Platform Memory Bank +7

- Agent Platform Memory Bank (72): OAuth 2.0 with IAM and service accounts (30), less 10, as for the other Google API listings, because the v1 discovery document lists `access_token`, `oauth_token` and `key` as query parameters (20 of 30). IAM Conditions can restrict access by memory scope; purge and delete have no confirmation (15 of 20). Memories are written by an LLM from conversation content and returned to agents, with no injection guidance found (5 of 15). Access Transparency and Access Approval are listed; Cloud Audit Logs coverage for Memory Bank wasn't read (12 of 15). Google's valid security.txt, vulnerability reward programme and certifications, with HIPAA listed for Memory Bank (20). Total 72.
- Hindsight (65): Keys can be restricted to named banks, expire after an hour to a year or never, are revocable with child keys revoked alongside, and the docs give a rotation procedure. The hosted MCP uses OAuth with PKCE under RFC 9728, or a Bearer key (30). Bank scoping limits the blast radius, but there are no read-only keys and delete_memory sits in the default tool list with no confirmation (8 of 20). `Memory Defense` screens every retain before storage. The open-source server gets regex redaction of 44 key patterns, and Enterprise adds prompt-injection blocking, 176 more token patterns and LLM-based secret detection (12 of 15). Security audit trails and SIEM webhooks are Enterprise only (5 of 15). These four lines per the 1 October check, not re-read on 4 November (docs.hindsight.vectorize.io answers robots.txt with its app page). SECURITY.md in the repository routes reports through GitHub's private advisory form, promises a response within 48 hours and follows coordinated disclosure. No security.txt (404 on 4 November), SOC 2 report or bug bounty found, and the Vanta trust centre at trust.vectorize.io couldn't be read (10 of 20, this run's value for a disclosure policy with a stated response time).

## Verdicts

**Agent Platform Memory Bank.** Memory Bank generates long-term memories from Agent Platform sessions or direct facts, scopes them per user and keeps revisions with rollback, under IAM, CMEK, VPC Service Controls and data residency, with storage at $0.30 per GiB-month. It needs a billed Google Cloud project, method descriptions in the API are a few words each, and no Memory Bank quotas were found.

**Hindsight.** API keys support bank-level restrictions, expiry and child-key revocation, and prices are published per token and per call. The status page and docs couldn't be read, 1.x minor releases carried breaking changes without notice, and access-control fixes shipped without advisories.

## Before you call either

### Agent Platform Memory Bank

1. Run `memories.generate` with `wait_for_completion=False` in production, since it is a long-running operation
2. Always pass a `scope` such as {"user_id": ...} so one user's memories never reach another
3. Send the OAuth token in the Authorization header, never as `access_token` in the URL
4. Expect a 404 when fetching a deleted memory and treat it as gone
5. Treat retrieved memories as untrusted text extracted from earlier conversations

### Hindsight

1. Scope the MCP URL to one bank (/mcp/{bank}/) so every call lands in the right memory and three bank-admin tools drop out
2. Use recall for lookups and keep reflect ($0.05 a call) for questions that need reasoning
3. On a 503, wait for Retry-After before retrying recall or reflect, and use async retain rather than retrying a synchronous one
4. Treat HTTP 402 as out of credit and 403 as a key that can't reach that bank
