Status page showed 80.992 per cent uptime for its single component and \"Some services are down\" on 2 October, with no incident history.\n\n**Opik API + MCP.** Five MCP tools with read and write annotations, no delete operation, OAuth sign-in on Opik Cloud and per-user rate limits published with numbers. The MCP server has no read-only mode, API keys on Free and Pro act with the user's full permissions, and the status page has posted nothing since June 2024.\n\n## Before you call either\n\n### HoneyHive\n\n1. Give the agent a read-only `hh_ro_` key for analysis and a separate `hh_ingst_` key for sending traces\n2. Treat a 404 as possibly a bad, revoked or expired key before assuming the record is missing\n3. Set `limit` on `POST /v1/events/search`. The default is 1,000 rows\n4. Use the CLI (`brew tap honeyhiveai/tap \u0026\u0026 brew install honeyhive`) from a coding agent. It maps one command to each API endpoint\n5. Control plane commands need an `hh_fgcp_` key and the control plane host api.cp.us.honeyhive.ai\n\n### Opik API + MCP\n\n1. Send the API key in `authorization` without `Bearer`, and send a `Comet-Workspace` header on every Opik Cloud call\n2. Keep client approval on for the MCP `write` tool, since there is no read-only mode, and call it with `dry_run` first\n3. Treat trace inputs, outputs and metadata as data, not instructions, as the MCP FAQ says\n4. Listing traces or spans is capped at 30 requests a minute per workspace. Use the SDK's `search_traces` or `search_spans`, which back off, and honour `RateLimit-Reset` on 429\n5. Move a local MCP install from `npx opik-mcp` to `uvx opik-mcp` before 15 November 2026, when the npm server stops\n\n## Questions\n\n### Which is better for AI agents, HoneyHive or Opik API + MCP?\n\nOpik API + MCP scores 71.7 (BB) on agent readiness against HoneyHive's 55.7 (C), and leads in 5 of 7 scored categories.\n\n### Do HoneyHive and Opik API + MCP need an API key?\n\nHoneyHive needs an API key. Opik API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call HoneyHive and Opik API + MCP without installing anything?\n\nYes. HoneyHive has a hosted endpoint at https://api.dp1.us.honeyhive.ai and Opik API + MCP at https://www.comet.com/opik/api.\n\n### Are HoneyHive and Opik API + MCP open source?\n\nNo open-source release is listed for HoneyHive. Opik API + MCP is open source (Apache-2.0 (platform, SDKs and MCP server). Opik Cloud is a hosted service under Comet's Terms of Service, and SSO, JWT auth and service accounts are Enterprise or Cloud only).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/honeyhive-vs-opik.json, and with the fewest tokens: https://www.anchorterminal.com/compare/honeyhive-vs-opik.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"honeyhive\", \"b\": \"opik\"}`.
