What you can do with this MCP connector
4399 Open Platform MCP Server lets your AI agent handle all the heavy lifting for your H5 and mobile games. You can use this to manage user logins, check payment statuses, and keep track of everything in the 4399 ecosystem without needing a developer on call. This server gives your agent tools for everything from user profiles to global leaderboards. validate_login checks if a user's session is active when you hand it an access token. query_order gets the current status and full details for any payment order ID. get_user_info pulls basic profile info and registration data using a unique user ID.
Your agent can list_friends to pull a list of friends connected to a specific 4399 user. The check_sensitive_words tool scans text inputs, like chat messages or role names, filtering out any prohibited or sensitive words. You can get_leaderboard to fetch the top list of players for a specific leaderboard, and you'll submit_score a new record to that same global leaderboard. get_server_time gives the current timestamp from the 4399 server.
You can also get_game_status to check the current operational status of the connected game.

What Changes When You Connect
- Eliminate manual payment checks. Use
query_orderto get real-time status for any recharge transaction, confirming whether payment went through before a player spends in-game currency. - Keep your community safe.
check_sensitive_wordsscans all user-generated content—chat, role names—to filter out prohibited terms before they appear in the game. - Maintain leaderboard accuracy. Use
submit_scoreto push new records andget_leaderboardto pull the current top 100, keeping competitive data consistent. - Stop guessing user status.
validate_loginconfirms if a user's session is active with a token, preventing access issues and dead-end user flows. - Improve player onboarding.
get_user_infoquickly pulls basic profile data andlist_friendsshows who the player is connected with, making account setup faster. - Handle time differences reliably.
get_server_timeensures all your recorded events and score submissions use the official 4399 server time, avoiding time zone bugs.
Real-World Use Cases
Processing a New Purchase
A user buys premium currency. Instead of waiting for manual confirmation, the agent runs query_order with the transaction ID. The agent confirms the status is 'completed' and immediately tells the game server to credit the player's account, solving the delay between payment and in-game access.
Banning a Toxic Player
A moderator reports a player for abusive chat. The agent first runs check_sensitive_words on the chat log. If terms are flagged, the agent uses get_user_info to pull the account details and automatically flags the account for review, stopping abuse before it spreads.
Updating a High Score
A player completes a difficult level. The agent calls submit_score with the new record and then runs get_leaderboard to verify the player's new rank. This confirms the score was accepted and shows the immediate competitive impact.
Verifying a Game Bug
A player reports that their profile data seems wrong. The agent uses get_user_info to pull the official record. If the data doesn't match what the player claims, the agent can compare it against the get_server_time to check for potential synchronization issues.
The Tradeoffs
Checking status in separate systems
A developer has to check the payment system's API, then the user database's API, then the leaderboard's API, all in separate functions, which is brittle and complex to maintain.
→
Use the agent to orchestrate the calls. For example, run query_order to validate payment, then get_user_info to pull the profile, and finally validate_login to ensure the user is currently active. This keeps the logic centralized.
Manually enforcing content rules
Writing regex or keyword lists into your own application to filter chat or role names. These lists are always incomplete and miss new slang or prohibited terms.
→
Run check_sensitive_words. This uses the 4399 platform's official, updated policy to filter content for you. It's the proper way to guard chat and names.
Assuming data consistency
Running get_user_info and then assuming the user is logged in. You might miss a stale session, leading to failed game logic or incorrect data access.
→
Always run validate_login before making any critical calls. This ensures the user's session is genuinely active before you query their profile or submit a score.
When It Fits, When It Doesn't
Use this if you need to manage cross-platform, high-volume gaming data. Specifically, if you need to: 1) Reconcile payments (query_order) with user actions (get_user_info), or 2) Enforce rules based on the 4399 ecosystem's official policies (check_sensitive_words).
Don't use this if your problem is purely internal (e.g., calculating a score based on local server data). For those cases, a simple data calculation tool is better. You must use this if your tools rely on the 4399 backend for authentication or payment data, because it gives you the official access points.

Available Capabilities
Manually checking payment status and user data is a mess.
Right now, if a player buys something, you're juggling three screens: the payment provider dashboard, the user database, and the game console. You have to copy order IDs, switch tabs, and wait for each system to update before you can tell if the player actually got their items. It's slow, and things break.
With the 4399 Open Platform MCP Server, you just ask the agent. It runs `query_order` to check the payment status, then `get_user_info` to confirm the user exists. It handles the multi-system lookup and gives you a clean 'success/fail' answer, instantly.
Get game status and user details with 4399 Open Platform MCP Server
You currently have to call the 4399 API endpoints individually for logins, friend lists, and game status. This requires writing a lot of boilerplate code just to manage credentials and error handling across multiple API calls.
Now, you connect the MCP Server. You just tell your agent to check the status, and it handles the entire connection, authentication, and data retrieval process for you. It’s cleaner, faster, and less code.
Common Questions About 4399 Open Platform MCP
How do I check payment status using the query_order tool? +
Just provide the transaction ID to query_order. It returns the full details, including the current status (like 'completed' or 'pending') and the amount in CNY. This is your single source of truth for payments.
Does validate_login check if a user is active? +
Yes, validate_login confirms if the user's session is still valid. It uses the client-side SDK token to confirm if the login session is good for continued use.
Can I use check_sensitive_words for chat filtering? +
Yes. check_sensitive_words scans content against the official 4399 policy. It flags prohibited terms for role names or public chat, which is exactly what you need for moderation.
What is the difference between get_user_info and list_friends? +
get_user_info fetches core profile data for a user ID. list_friends specifically pulls the network list of friends connected to that user, showing their social circle.
How do I use `submit_score` to update a player's leaderboard record? +
You call submit_score with the player's UID, the new score, and the leaderboard ID. The tool submits the record directly to the 4399 server, making it visible in the global leaderboard shortly after submission.
What should I do if `validate_login` fails or returns an error? +
If validation fails, the user's session token or credentials are bad. You must prompt your agent to check the user's source credentials or refresh the token before retrying the validation.
Can `get_leaderboard` be used to filter by specific player criteria? +
No, get_leaderboard fetches the top players list based on the defined ranking rules. If you need to search for a specific player, use get_user_info first to verify their UID.
Does `get_server_time` help with time zone discrepancies? +
Yes, get_server_time provides the current 4399 server timestamp. This helps your agent ensure that any recorded action or score is timestamped accurately relative to the game's official server clock.
How do I validate a user login token from my backend? +
Use the validate_login tool with the user's uid and the access_token provided by the 4399 SDK. The agent will confirm if the session is legitimate and return the authentication code.
Can I check the status of a specific payment order? +
Yes! Use the query_order tool with the 4399 order ID. Your agent will retrieve the transaction status, amount, and timestamp from the payment gateway.
Does it support high score submission? +
Yes! The submit_score tool allows your agent to update the high score for a specific user ID on the configured 4399 leaderboard.
