Verdicts

Galileo API + MCP

OpenAPI 3.1 spec with 184 paths and 244 operations. No status page, no published rate limits and no SLA.

HoneyHive

Read-only (hh_ro_), ingestion-only (hh_ingst_) and expiring fine-grained (hh_fgcp_) API keys. Status page showed 80.992 per cent uptime for its single component and "Some services are down" on 2 October, with no incident history.

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

HoneyHive

  1. Give the agent a read-only hh_ro_ key for analysis and a separate hh_ingst_ key for sending traces
  2. Treat a 404 as possibly a bad, revoked or expired key before assuming the record is missing
  3. Set limit on POST /v1/events/search. The default is 1,000 rows
  4. Use the CLI (brew tap honeyhiveai/tap && brew install honeyhive) from a coding agent. It maps one command to each API endpoint
  5. Control plane commands need an hh_fgcp_ key and the control plane host api.cp.us.honeyhive.ai

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
