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
