Verdicts
Helicone AI Gateway + MCP
One base-URL change gives logging, caching, fallbacks and rate limits for 100+ models. Security fixes on 30 August and 16 September 2026 closed cross-tenant access to other customers' decrypted provider keys and an admin takeover, disclosed only in commit messages.
Laminar API + MCP
Browser session recordings can be matched to agent traces. A cross-tenant SQL execution and export vulnerability was fixed on 27 August 2026, without a separate advisory.
Before you call either
Helicone AI Gateway + MCP
- Bring your own provider keys. Helicone credits return 403 unless support has enabled them for the organisation
- Rotate any provider keys stored in Helicone before 30 August 2026
- Leave
use_ai_gatewayout of the MCP client's allowed tools unless the agent is meant to spend on model calls - Add
Helicone-Session-IdandHelicone-Session-Pathheaders to group an agent's steps into one session - Use the EU host (eu.helicone.ai) if the account was created there
Laminar API + MCP
- Use
query_laminar_sqlto find trace IDs, thenget_trace_contextfor a compact summary of one run - Always add a time range and
LIMITto SQL. Server caps on time, memory and result size reject wide scans - On 429 from the SQL API, back off. The per-project limit isn't published
- Set
flush_by_sizewhen spans carry whole conversation histories, or large batches get rejected - Keep the project API key in a header, not in the URL
