• src/tools/retrieve-connections.ts:11-99 (handler)

  The RetrieveConnectionsTool class defines the tool implementation, including the name 'retrieve_connections', operationName, Zod input schema for validation, detailed inputSchema for the Tool interface, and description.
  export class RetrieveConnectionsTool extends OperationTool< TRetrieveConnectionsParams, TRetrieveConnectionsResult[] > { public override readonly name = 'retrieve_connections'; public override readonly operationName = OPERATION_NAME.retrieveConnections; protected override readonly schema = z.object({ limit: z.number().min(1).max(1000).optional(), filter: z .object({ firstName: z.string().optional(), lastName: z.string().optional(), position: z.string().optional(), locations: z.array(z.string()).optional(), industries: z.array(z.string()).optional(), currentCompanies: z.array(z.string()).optional(), previousCompanies: z.array(z.string()).optional(), schools: z.array(z.string()).optional(), }) .optional(), }); public override getTool(): Tool { return { name: this.name, description: 'allows you to retrieve your connections and perform additional person-related actions if needed (st.retrieveConnections action).', inputSchema: { type: 'object', properties: { limit: { type: 'number', description: 'Optional.

• src/linked-api-tools.ts:34-67 (registration)

  The LinkedApiTools class constructor instantiates RetrieveConnectionsTool (line 40) and registers it in the readonly tools array.
  constructor(progressCallback: (progress: LinkedApiProgressNotification) => void) { this.tools = [ // Standard tools new SendMessageTool(progressCallback), new GetConversationTool(progressCallback), new CheckConnectionStatusTool(progressCallback), new RetrieveConnectionsTool(progressCallback), new SendConnectionRequestTool(progressCallback), new WithdrawConnectionRequestTool(progressCallback), new RetrievePendingRequestsTool(progressCallback), new RemoveConnectionTool(progressCallback), new SearchCompaniesTool(progressCallback), new SearchPeopleTool(progressCallback), new FetchCompanyTool(progressCallback), new FetchPersonTool(progressCallback), new FetchPostTool(progressCallback), new ReactToPostTool(progressCallback), new CommentOnPostTool(progressCallback), new CreatePostTool(progressCallback), new RetrieveSSITool(progressCallback), new RetrievePerformanceTool(progressCallback), // Sales Navigator tools new NvSendMessageTool(progressCallback), new NvGetConversationTool(progressCallback), new NvSearchCompaniesTool(progressCallback), new NvSearchPeopleTool(progressCallback), new NvFetchCompanyTool(progressCallback), new NvFetchPersonTool(progressCallback), // Other tools new ExecuteCustomWorkflowTool(progressCallback), new GetWorkflowResultTool(progressCallback), new GetApiUsageTool(progressCallback), ]; }
• src/tools/retrieve-connections.ts:17-31 (schema)

  Zod schema for validating the input parameters of the retrieve_connections tool: optional limit and detailed filter object.
  protected override readonly schema = z.object({ limit: z.number().min(1).max(1000).optional(), filter: z .object({ firstName: z.string().optional(), lastName: z.string().optional(), position: z.string().optional(), locations: z.array(z.string()).optional(), industries: z.array(z.string()).optional(), currentCompanies: z.array(z.string()).optional(), previousCompanies: z.array(z.string()).optional(), schools: z.array(z.string()).optional(), }) .optional(), });
• src/utils/linked-api-tool.ts:39-58 (helper)

  The execute method from the base OperationTool class, inherited by RetrieveConnectionsTool, which locates the specific retrieveConnections operation and executes it with progress reporting.
  public override execute({ linkedapi, args, workflowTimeout, progressToken, }: { linkedapi: LinkedApi; args: TParams; workflowTimeout: number; progressToken?: string | number; }): Promise<TMappedResponse<TResult>> { const operation = linkedapi.operations.find( (operation) => operation.operationName === this.operationName, )! as Operation<TParams, TResult>; return executeWithProgress(this.progressCallback, operation, workflowTimeout, { params: args, progressToken, }); } }
