Plugins can add extra capabilities to Agent applications. For example, plugins such as online search or video processing can enhance an Agent’s functionality, increase its practicality, and expand its service boundaries. You can browse existing plugins in the Plugin Marketplace or connect your own MCP plugin for Agents to call.
You can add plugins to Agents in Multi-Agent Mode, or call plugin services in Single-Workflow Mode by adding a plugin node, thereby extending the Agent’s service boundaries.

A plugin is a toolset that can contain one or more tools. Plugins are categorized into the following three types:
Plugin Types
API Type: Based on the OpenAPI 3.0 specification. API plugins provide standardized interfaces. By defining clear input and output structures, API services allow systems and tools to interact via HTTP requests. With standardized interfaces, other applications or plugins can easily call and use these functions.
MCP Type: MCP (Model Context Protocol) is an open protocol designed for LLM applications to seamlessly integrate with external data sources and tools. MCP provides a unified interface standard, simplifying scattered API plugins into a true “plug-and-play” model. This addresses challenges in traditional API integration such as multi-protocol adaptation and high development costs.
Code Type: Based on a Python environment. Provides services through user-written Python functions, allowing users to implement APIs by writing Python code.
The Plugin Marketplace offers three sources of plugins:
Official Plugins: Provided by the Tencent Cloud Agent Development Platform. These can be directly applied to your applications to expand their capabilities.
Third-party Plugins: Listed in the marketplace but developed by third parties (e.g., enterprises, open-source communities, independent developers).
Custom Plugins: If the available plugins do not meet your needs, you can create your own custom plugins. By registering tools/plugins based on the OpenAPI 3.0 specification in the Tencent Cloud Agent Development Platform, they become available as custom plugins during application configuration. See Creating Plugin for details.
Note:
Tencent Cloud Agent Development Platform will continue to add high-quality third-party plugins to enrich the marketplace. However, it cannot guarantee or be held responsible for the security or stability of third-party services.
Note:
Currently, the Plugin Marketplace is in a limited-time free trial. During this trial, plugin calls are subject to concurrency limits. For additional capacity, please contact Tencent Cloud customer service.
