MCP TypeScript SDK: Server bearer authentication accepted tokens issued for another service
### Summary In affected versions, the SDK's server-side bearer authentication had no way to check that a token was issued for your server (its audience). Where one authorization server issues tokens for several services, a valid token for another service was also accepted by your MCP server. ### Am I affected? Yes, if your HTTP server uses `requireBearerAuth()` or `verifyBearerToken()`, its authorization server also issues tokens for other services, and your `verifyAccessToken()` does not check the token's audience (`aud`) itself. Affected versions: - `@modelcontextprotocol/sdk` 1.6.0 through 1.31.0 - `@modelcontextprotocol/server` 2.0.0 t
- Обновитесь до 2.3.1
