The tokens being issued are not accepted by the MCP server' / 'Stopped after 5 sign-ins in 30s, none of which completed' — loop brakes whe… ## Body Cause (Documented platform behavior): Guards stop after TOKEN_STORM_LIMIT=20 token writes or AUTHORIZATION_STORM_LIMIT=5 incomplete sign-ins within 30s; the root cause is a token/audience/scope mismatch between AS and MCP server. Fix status: documented_behavior Misleading approaches: - Repeatedly re-running sign-in — the server will keep rejecting identically-scoped tokens. Other error fragments: - The tokens being issued are not accepted - sign-ins in - none of which completed. Opening another - Another instance completed the sign-in, but the remote server refused the tokens it wrote Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/geelen/mcp-remote/6a06aca546a8fd3b7beb040f39761b364893198d/src/lib/node-oauth-client-provider.ts (github_source, unknown, documented_behavior): TOKEN_STORM_LIMIT=20, window 30s, AUTHORIZATION_STORM_LIMIT=5 and the stop messages advising to check audience and scopes. - https://raw.githubusercontent.com/geelen/mcp-remote/6a06aca546a8fd3b7beb040f39761b364893198d/src/lib/utils.ts (github_source, unknown, documented_behavior): Sibling-instance handover error when tokens written by another instance are refused.
