This information is not required, but it makes it easier for our Community members and support team to help you. Application Affected Claude AI > Dropbox via mcp.dropbox.com Question or Issue Does the hosted MCP server at mcp.dropbox.com expose any file write tools (upload, create, delete)? If not, is that on the roadmap? I have 'files.content.write' checked under individual scopes but my connector can only seem to read and not save files.

sharing/list_file_members do NOT return time_last_seen of members
Hi! I'm trying to use the sharing/list_file_members in order to fetch the last time a shared file have been seen by its member. According to the API, the response for each member should include the field time_last_seen, in case the member have opened the file. However, it does not matter if members have opened it or not, the field is not being returned at all in the response. Am I missing anything? This is the API I'm doing: curl -X POST "https://api.dropboxapi.com/2/sharing/list_file_members" --header "Content-Type: application/json" \ --header "Authorization: Bearer <AUTH_TOKEN>" --header "Dropbox-API-Select-User: <USER_ID>" --data "{\"file\": \"<FILE_ID\"}"
/files/save_url has high rate of failure
Hi, I am currently testing using the /files/save_url API endpoint and am experiencing a high rate of failure. I am testing using a set of 6 small image files stored in S3-compatible storage environments, and using their public URLs with the aforementioned API endpoint. In every test run, there is at least one file that fails to be created in Dropbox, and it is a different file from the set each time. A file that fails in test #1 will succeed in tests #2, #3 and fail again in test #4 etc. These image files are standard .jpg files and generally 500kb or less. Upon checking the status of the API requests using /files/save_url/check_job_status, the failed IDs return the "download_failed" response. I know there is a 5 minute limit on file transfers using /files/save_url, however all these failed IDs are returning their failure response only a few seconds after initiating the API request. It may be worth mentioning that the API requests to /files/save_url are occurring all together. I don't believe the URLs are being rate-limited on the S3-compatible storage side, as it is tested with multiple environments, including self-hosted storage without such restrictions. Done some googling, found some users with the same issue, but unable to find anything that resolves the issue. Some example failed job IDs: nJekCKfZPnwAAAAAAAAAAQ aPQH1k_ei7cAAAAAAAAAAQ Is there a way to resolve this issue?Using API and SDK together
Hello, I need some help until now i have been using >NET SDK Version 6.37. and we are experiencing a problem downloading large files 30GB and higher. so I tried to implement chunk download, but SDK does not support it . so I did it using the API. but my problem is that when we use the SDK we do not Need to refresh token. and when we use api after some time I am getting 401 . so I implemented a refresh token method, and refreshed the token , but still after sending the request again with the new token I got I am still getting the 401. I tried to get the token from the Dropbox Client but it is not there also regarding the refresh token , is this token always stays the same ? can some one help? adding some code snipped. public async Task<string> RefreshAccessTokenAsync(string expiredAccessToken,BaseRequest baserRequest,bool isBusinessClient, CancellationToken token) { using (var http = new HttpClient()) { var request = new HttpRequestMessage(HttpMethod.Post, "https://api.dropboxapi.com/oauth2/token"); var content = new FormUrlEncodedContent(new Dictionary<string, string> { { "grant_type", "refresh_token" }, { "refresh_token", baserRequest.RefreshToken }, { "client_id", isBusinessClient ?ClientIdBusiness : ClientId }, { "client_secret", isBusinessClient ?

I am sending a request using this endpoint: https://api.dropboxapi.com/2/files/list_folder And sending this data: { "path": "/Otter+Moon", "include_media_info": true, "include_has_explicit_shared_members": false, "include_mounted_folders": true } However, the media info is not being returned. This means that I have to send individual https://api.dropboxapi.com/2/files/get_metadata { "path": "/Otter+Moon/EmmaWolf_OtterandMoon-1.jpg", "include_media_info": true } for each file in that directory. Why? Why is the media info not being returned on the initial request?
the names of the Certificate Authorities (CAs) changed
Hello Dropbox Developer Support, I am reviewing the recent root certificate changes described here:https://dropbox.tech/developers/api-server-certificate-changes We do not use an official Dropbox SDK, so we will not be directly affected by the root certificate change itself. However, I would like to confirm that the updated root and intermediate CA certificates are present in our trusted CA store. Could you please provide the names of the Certificate Authorities (CAs) for the following? - The new root certificate(s) - The updated intermediate certificate(s) This will help us verify trust chain presence in our environment. Thank you in advance. Best regards,
