Constructors

constructor

new McpToolset(config, toolFilter?): McpToolset
Parameters
- config: McpConfig
- toolFilter: string[] | ((tool: any, context?: ToolContext) => boolean) = null
Returns McpToolset
- Defined in packages/adk/src/tools/mcp/index.ts:43

Methods

initialize

initialize(): Promise<McpClientService>
Initializes the client service and establishes a connection.

Returns Promise<McpClientService>
- Defined in packages/adk/src/tools/mcp/index.ts:78

setSamplingHandler

setSamplingHandler(handler): void
Set a sampling handler for this MCP toolset. This allows MCP servers to request LLM completions through your ADK agent.
Parameters
- handler: SamplingHandler
  ADK sampling handler that receives ADK-formatted messages
Returns void
- Defined in packages/adk/src/tools/mcp/index.ts:99

removeSamplingHandler

removeSamplingHandler(): void
Remove the sampling handler

Returns void
- Defined in packages/adk/src/tools/mcp/index.ts:114

getTools

getTools(context?): Promise<BaseTool[]>
Retrieves tools from the MCP server and converts them to BaseTool instances. Similar to Python's get_tools method.
Parameters
- Optionalcontext: ToolContext
Returns Promise<BaseTool[]>
- Defined in packages/adk/src/tools/mcp/index.ts:128

convertADKToolsToMCP

convertADKToolsToMCP(tools): any[]
Converts ADK tools to MCP tool format for bidirectional support
Parameters
- tools: BaseTool[]
Returns any[]

refreshTools

refreshTools(context?): Promise<BaseTool[]>
Refreshes the tool cache by clearing it and fetching tools again
Parameters
- Optionalcontext: ToolContext
Returns Promise<BaseTool[]>
- Defined in packages/adk/src/tools/mcp/index.ts:203

close

close(): Promise<void>
Closes the connection to the MCP server. Similar to Python's close method.

Returns Promise<void>
- Defined in packages/adk/src/tools/mcp/index.ts:212

dispose

dispose(): Promise<void>
Disposes of all resources. This method should be called when the toolset is no longer needed. Provides alignment with disposal patterns common in TypeScript.

Returns Promise<void>
