ByteDance Services: MCP Service Description

Service Overview

ByteDance Services is a high-performance, reliable MCP (Model Context Protocol) service designed to simplify encryption, decryption, and signature management for TikTok ecosystem integration. It aggregates essential tools to handle core security and data processing tasks, enabling developers to focus on building features rather than troubleshooting complex encryption logic. With blazing fast speed and consistent reliability, it ensures seamless compatibility with TikTok’s API requirements, reducing development time and enhancing application stability.

Tool Names & Functions

ByteDance Services includes 12 specialized tools to address key workflows:

Report String Decode: Decodes encoded values from the ri/report protobuf.
MSSDK Decrypt: Decrypts hex-encoded buffers using keys 0–4 (requires raw, delimiter-free hex payloads).
MSSDK Encrypt: Encrypts hex-encoded buffers using keys 0–4 (outputs payloads for request protobufs).
Ladon Decrypt: Decrypts the X-Ladon header from TikTok app requests.
Ladon Encrypt: Encrypts the X-Ladon header for TikTok app requests.
Generate X-Cylons: Generates X-Cylons headers for websockets across MSSDK platforms.
TTEncrypt: Encrypts hex payloads with optional local compression (compression required for device_register requests).
Generate Signature: Generates X-Argus, X-Ladon, X-Gorgon, and X-Khronos headers (adapts to logged-in state; supports custom X-SS-Stub).
Argus Decrypt: Decrypts the X-Argus header from TikTok app requests.
TTDecrypt: Decrypts TTEncrypt hex payloads with optional local decompression (decompression required for device_register requests).
Generate Risk Report Field 66: Generates field 66 for ri/report protobufs (flags set to 0 to mark debug checks as successful).
Report String Encode: Encodes values for inclusion in the ri/report protobuf.

Tool Introduction

Each tool is built to solve specific pain points, prioritizing ease of use:

Report String Decode/Encode eliminates manual protobuf parsing, letting users quickly extract or insert values.
MSSDK Decrypt/Encrypt work with raw hex payloads (no protobuf loading needed), simplifying MSSDK data handling.
TTEncrypt/TTDecrypt include compression/decompression options, with clear guidance for device_register requests to ensure correct payloads.
Generate Signature adapts to logged-in states and supports custom X-SS-Stub, covering scenarios from early-stage device registration (minimal parameters) to authenticated requests.
Ladon/Argus tools handle header encryption/decryption, while Generate X-Cylons simplifies websocket security setup.
Even niche needs, like Generate Risk Report Field 66, are addressed with pre-configured success flags, reducing errors.

Application Scenarios & Integration Advantages

Use Cases

Ideal for developers building TikTok-related applications (e.g., third-party tools, analytics platforms, custom clients). It supports:

Processing encrypted API requests/responses.
Securing websocket connections with X-Cylons.
Generating compliant security headers (X-Argus, X-Ladon, etc.).
Handling data from TikTok’s ri/report protobufs.

Integration Advantages

Leveraging MCP’s standardized protocol, ByteDance Services ensures seamless tool interoperability. Developers avoid redundant encryption code, cutting time-to-market. Its adherence to TikTok’s specifications guarantees compatibility, minimizing errors. Scenario-based guidance (e.g., device_register vs. logged-in requests) lowers the learning curve, making advanced security features accessible to all skill levels.

ByteDance Services empowers developers to build robust, compliant TikTok integrations—fast, reliably, and with minimal complexity.

Tools (12)

Report String Decode

Decodes an encoded value from the ri/report protobuf.

MSSDK Decrypt

Decrypts a buffer encoded in hexadecimal using the requested key. Valid keys are 0, 1, 2, 3, 4. **This endpoint doesn't load the protobuf. You must provide the mssdk encrypted data contained in a no-delimiter hexadecimal payload as is in the example.** The returned data is the decrypted payload.

MSSDK Encrypt

Encrypts a buffer encoded in hexadecimal using the requested key. Valid keys are 0, 1, 2, 3, 4. The returned data is the mssdk encrypted payload which must be placed inside of a request protobuf.

Ladon Decrypt

Decrypts the X-Ladon header from the TikTok app.

Ladon Encrypt

Encrypts the X-Ladon header from the TikTok app

Generate X-Cylons

Generates the X-Cylons header for use with websockets on any mssdk platform. **Important**: Please check out the two examples provided as each one describes a specific scenario (handshake and communication) that takes in different parameters.

TTEncrypt

Encrypts a hexadecimal payload with TTEncrypt with the option to compress the payload locally. For device_register requests compress must be set to true

Generate Signature

Generates the 4 signature headers (X-Argus, X-Ladon, X-Gorgon, X-Khronos) for a request. The parameters to this endpoint differ if you are logged in or not. Check out the multiple examples provided on the data that needs to be passed in depending on the logged in state. This endpoint also accepts the option for providing your own X-SS-Stub if you can't or don't want to provide your payload (check out example "Stub Provided") Certain endpoints that are invoked early (e.g device register) don't contain a lot of device parameters so it's important to leave them out (check out example "Device Register")

Argus Decrypt

Decrypts the X-Argus header from the TikTok app.

TTDecrypt

Decrypts a ttencrypted hexadecimal payload with the option to decompress the payload locally. For device_register requests decompress must be set to true to obtain the original json

Generate Risk Report Field 66

Generates field number 66 (debug check) to be used inside of the ri/report protobuf. The flags should all be set to 0 to mark all debug checks as successful.

Report String Encode

Encodes a value to be filled inside of the ri/report protobuf.
