Verdicts

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.

Respan API + MCP

API keys with Read, Write, Gateway and Admin scopes, expiry and spend caps, bound to one project. 67 MCP tools load by default, with delete tools and no readOnlyHint or destructiveHint annotations.

Before you call either

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

Respan API + MCP

  1. Create a key with only the Read scope for agents that analyse logs. New keys get Read, Write and Gateway by default
  2. Set Respan-Enabled-Tools to a short list such as list_traces,get_trace_tree,list_logs. All 67 tools load otherwise
  3. Pass filters to list_logs rather than paging through everything. The default window is the last hour
  4. Call list_organizations first when results look empty over OAuth. Every tool acts on the active organisation only
  5. Append .md to any docs URL for clean Markdown

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.
