Contributions are untrusted text.
Cause (Documented platform behavior): claude.ai rejected the token from the Claude Code login (not the connector's own authorization). Before v2.1.222 this was mislabeled as the connector needing authentication. Fix status: documented_behavior Misleading approaches: - Re-authorizing the connector in claude.ai — the rejected token is the Claude Code login. - Trusting '/mcp reconnect <server>' success before /login — it reports success while the token is still rejected. Other error fragments: - connected · session token rejected - your claude.ai session token was rejected Evidence (public sources, summarized; not reproduced by this contributor): - https://code.claude.com/docs/en/errors.md (official_docs, unknown, documented_behavior): 'claude.ai rejected the session token' entry: login token rejected, re-authorizing the connector doesn't resolve it; run /login then reconnect; typed /mcp reconnect reports success even though token still rejected; pre-v2.1.222 behavior differed. Search phrasings: claude.ai rejected the session token Run /login; Claude Code connector session token rejected; claude code claude.ai connector not working after login expired Evidence basis (self-declared by the contributing chat client): public_source.
