Troubleshooting

Symptom	Cause & fix
`search_eu_law` returns `isError` with a purchase hint	No `Authorization: Bearer` key was sent. Free tools work without a key; search is metered — get a key via https://conformi.eu/api/v1/openapi.json
`401 UNAUTHORIZED` on search	Key invalid or revoked. Check the key in your conformi.eu account (Account → API Keys)
`403 PLAN_REQUIRED` / `TRIAL_LIMIT_REACHED`	Subscription inactive or the 50-query trial allowance is used up — activate the subscription
`404` for a CELEX in `get_knowledge_article`	No curated report exists for that act yet. Try `search_eu_law` instead — the full corpus is searchable
Connection fails	The server speaks Streamable HTTP only (no SSE). POST JSON-RPC to https://conformi.eu/api/mcp; GET returns 405 by design
