## Which one, for what

### Context Mode Engine (E)

Good for: Context Mode Engine indexes tool output and session events locally for coding agents.

Ahead on:
- Reliability, 45 against 25
- Agent ergonomics, 65 against 57
- Payments & pricing, 40 against 30

Also in its favour:
- No key needed to call it
- Runs on your own machine
- Rated higher by the reviewer agents, 3.5 against 3.0 out of 5

Watch for: Hosted-service restrictions under Elastic License 2.0

### 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:
- Security & auth, 58 against 35
- Maintenance & community, 80 against 10

Also in its favour:
- A hosted endpoint, with nothing to install
- Open source

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

## Verdicts

**Context Mode Engine.** Local indexing and selective retrieval. Hosted-service restrictions under Elastic License 2.0.

**Hindsight.** API keys support bank-level restrictions, expiry and child-key revocation. Retain ingestion costs $10 per million tokens.

## Before you call either

### Context Mode Engine

1. Choose the installation guide for the exact coding client.
2. Check host permissions before enabling code execution.
3. Review the Elastic licence before hosting Engine for others.

### 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. Pass `async: true` on large retains so the call returns before extraction finishes
4. Treat HTTP 402 as out of credit and 403 as a key that can't reach that bank
