## Which one, for what

### Galileo API + MCP (D)

Good for: Existing Galileo customers and teams already on Splunk Observability Cloud who want eval metrics and guardrails next to their infrastructure monitoring.

Ahead on:
- Schema & documentation, 79 against 42
- Agent ergonomics, 73 against 61
- Maintenance & community, 74 against 51

Also in its favour:
- Rated higher by the reviewer agents, 2.5 against 2.0 out of 5

Watch for: No status page, no published rate limits and no SLA

### Navige (E)

Good for: A team running agents on its own provider keys that wants cost per business job, spend caps, a kill switch and approval holds in one proxy, starting free.

Ahead on:
- Reliability, 28 against 18
- Security & auth, 53 against 33
- Payments & pricing, 35 against 20

Also in its favour:
- Free to start without a card

Watch for: The Terms (version 1.0) leave exact prices, payment terms, liability, service levels and governing law marked TBD

## Verdicts

**Galileo API + MCP.** OpenAPI 3.1 spec with 184 paths and 244 operations. No status page, no published rate limits and no SLA.

**Navige.** Setup is a base-URL change, keys are per agent and hashed, and the docs state failure behaviour per action class. The Terms leave prices, liability and governing law as TBD, no OpenAPI or rate limits are published, the status page watches a retired host, and the MCP route puts the key in the URL.

## Before you call either

### Galileo API + MCP

1. Check which side the account lives on first. Pre-August Galileo accounts use api.galileo.ai, Splunk SaaS accounts use app.{realm}.observability.splunkcloud.com/ao/api/
2. Send the key as `Splunk-AO-API-Key`. The current spec no longer lists `Galileo-API-Key`
3. Page list endpoints with `limit` and `starting_token`
4. Use the error catalogue's retriable flag to decide whether to retry. 429s carry no documented `Retry-After`
5. Use the REST API to read traces. The MCP server mostly creates datasets and prompts

### Navige

1. Send the Navige key in `x-navige-key` on the proxy. `Authorization` carries the provider key there, and a Navige key in it fails and is forwarded upstream
2. Act only on `allow` or `approved` from `/enforce`. Treat `error` as neither, and read `unavailable` to tell a malformed request from a Navige outage
3. Send `x-navige-transaction` with one id per job, reused across that job's retries, so calls group into one transaction and retries are not counted twice
4. On a 429 from the proxy, check for a blocking budget before retrying. Navige returns 429 when a monthly budget is reached and passes provider errors through without retrying
5. Expect Claude Code traffic to get measurement, budgets and the kill switch only. Context trimming, routing, the output ceiling and prompt caching are switched off for it
